  Perl 6 - perl6   (Site not responding. Last check: 2007-10-20)
Perl 6 Essentials is the first book that offers a peek into the development of the new Perl language while it's still in flux.
Written by members of the Perl 6 core development team, the book covers the development not only of Perl 6 syntax but also Parrot, the language-independent interpreter developed as part of the Perl 6 design strategy.
And finally, the entire Perl community is invited to participate in the design and implementation of Perl 6.

 A Taste of Perl 6: | Linux Magazine
Quantum::Superpositions is the forerunner to Perl 6 junctions.
Like Perl 1 through 5, Perl 6 is evolving to meet the needs of its users, taking that which has proven widely useful or commonly necessary and making it part of the core language, relegating specialized and occasionally-used features to external modules, and consigning to oblivion those ideas that just didn't work.
Damian Conway (http://damian.conway.org) is a professional Perl boffin.

 CPAN/src
The important changes between Perl releases are recorded in the "perl delta pods".
The bug affects you only if you use an executable called 'suidperl', not if you use 'perl', and it is very likely only to affect UNIX platforms, and even more precisely, as of March 2001, the only platforms known to be affected are Linux platforms (all of them, as far as we know).
The problem was found both in Perl 4.036 (the final) (and last) release of Perl 4 and in early versions of Perl 5 (pre-5.003).

 Perl 6 - Wikipedia, the free encyclopedia
Perl 6 is a re-design of the language, introducing elements of many modern and historical languages.
Perl 6 grammar is distinct from Perl and not intended to be backwards-compatible, though a compatibility mode is part of the specification.
Perl 6 provides a superset of Perl 5 features with respect to regexes, folding them into a larger framework called "rules" which provide the capabilities of context-sensitive parsing formalisms (such as the syntactic predicates of parsing expression grammars and ANTLR), as well as acting as a closure with respect to their lexical scope.

 freshmeat.net: Editorials - Critique of Where Perl 6 is Heading
Perl 5 Man Pages are (or at least used to be) intended for experienced Unix system administrators and programmers who are already familiar with either Perl 4 or with the Unix toolset of shells, awk, and sed.
Perl 6 may be a good language to design 10 or 20 years from now, but it's certainly not one for this moment.
Perl 6 would be a non-solution to this problem because it gives an entirely new language for which new core documentation has to be written.

 oreilly.com -- Online Catalog: Perl 6 and Parrot Essentials, Second Edition
Distilling many years of Perl experience--including an insiders look at Perl development (the authors are members of the Perl 6 core development team)--Perl 6 and Parrot Essentials, 2nd Edition is an unparalleled preview of major changes in the widely-anticipated Perl 6.
Perl 6 and Parrot Essentials is the only book available to chart the course of the long but fruitful voyage of Perl 6.
Perl gurus and programmers alike will rely on this slim but essential book for both a clear view of the Perl horizon and to ensure they hit the ground running once this important new version of Perl is released.

 Perl - Wikipedia, the free encyclopedia
Perl is often used as a glue language, tying together systems and interfaces that were not specifically designed to interoperate, and for "data munging", converting or processing large amounts of data for tasks like creating reports.
Perl is implemented as a core interpreter, written in C, together with a large collection of modules, written in Perl and C. The source distribution is, as of 2005, 12 MB when packaged in a tar file and compressed.
Perl developers rely on the functional tests to ensure that changes to the interpreter do not introduce bugs; conversely, Perl users who see the interpreter pass its functional tests on their system can have a high degree of confidence that it is working properly.

 oreilly.com -- Online Catalog: Perl 6 Essentials
Perl continues to have a strong following devoted to its development, but in the meantime, a group of core Perl developers have begun working on Perl 6, a complete rewrite of the Perl language.
While Perl's creative philosophy and common-sense syntax are sure to remain in Perl 6, everything else in the language is being re-examined and recreated.
Written by members of the Perl 6 core development team, the book offers an explanation of the various stages of the project, with reference material for programmers who are interested in what changes are planned or who may want to contribute to the project.

 Cultured Perl: Perl 6 grammars and regular expressions
Perl 6 will run on top of Parrot, a versatile virtual machine that will be able to load and interpret not only Perl 6 bytecode, but many other languages as well.
Perl 6 regular expressions can easily specify "get the Nth time this happens," which was not easily possible in Perl 5.
Perl 6 Unicode support is much better than that in Perl 5 when it comes to regular expressions.

 Cultured Perl: Three essential Perl books
The future of Perl, that is. Perl 6 Essentials is a look ahead to the new Perl 6, and the authors promise yearly revisions to keep up with the rapid pace of Perl 6 development.
In addition, Chapter 6 has some instructions on how to get the engine parts into a whole new car, meaning that the choice of language is not exclusively Perl 6.
Perl 6 Essentials (O'Reilly and Associates, 2003) covers the development not only of Perl 6 syntax but also Parrot, the language-independent interpreter developed as part of the Perl 6 design strategy.

 Perl 6 and the Parrot Project
Perl 6 would be the community´s rewrite of Perl, and the community´s rewrite of itself.
The Perl 5 Porters (p5p) mailing list became the central clearing-house for bug reports or proposed changes to the Perl language, with the “pumpkin holder” (also known as the “pumpking”) being the programmer responsible for implementing the patches and distributing them to the rest of the list for review.
Although you might think that the birth of the Perl 6 project would be the first nail in the coffin for Perl 5, that´s far from the case.

 The Perl Foundation   (Site not responding. Last check: 2007-10-20)
What's missing is a comparatively small component to parse Perl 6 syntax and translate it to a form native to Parrot.
Because we can't expect Perl 6 design work to stop while implementation proceeds (even Perl 5 continues to evolve), we'll take a snapshot of the current state of the Perl 6 language specification at the start of the project.
The Perl 6 grammar engine (analogous to Perl 5's "regular expression engine") is the heart of the Perl 6 interpreter.

 Dr. Dobb's | Use Perl 6 Now | January 19, 2006
During the last Perl Whirl Geekcruise (http://www.geekcruise.com), I got to sit in on a Perl 6 talk by Allison Randal.
He's not aiming to make it into the final Perl 6 interpreter (which will be in Perl 6 itself), but until that's available, Pugs is what we have, and its what you can play with today to write real Perl 6 programs.
But that's not enough for me. Perl 6 is supposed to make everything an object, so I should get the same warm fuzzies that Smalltalk and Ruby give me. Let's see if I can treat a literal string as an object (which you can't do in Java, for instance, because it's not an object language).

 Developer Pipeline | TechWatch | Perl Gets An Extreme Makeover
In the summer of 2000, when the Perl community decided to go back to the drawing board, as opposed to merely pursuing incremental improvements to Perl's "State of the Onion," they embarked on an ambitious journey.
Other changes in the Perl 6 spec, with its descriptions of "slurpy arrays" and "splatty parameters," might make you wonder sometimes whether the folks steering the Perl ship are more mad scientists than language designers.
The Perl 6 RFC is the Perl community's "wish list" upon which Larry Wall based many of the new features in Perl 6.

Perl 6 will not be backwards compatible with any previous version of Perl, however thanks to Ponie (a Perl 5 on Perl 6 implementation) it will be able to act as though it is compatible with previous versions.
In early 2000, Chip Salzenburg began project Topaz, a rewrite of Perl 5 using C++ for the interpreter, with the intent that this would eventually be called Perl 6 ([1]).

 perl.com: What Is Perl 6
Perl 6 is the long-awaited redesign and reimplementation of the popular and venerable Perl programming language.
Perl 5 isn't perfect, though, and some of its flaws are more apparent the closer Perl 6 comes to completion.
Certainly there is a growing test suite that explores Perl's behavior in known situations, but too many of these tests exist to ensure that no one accidentally breaks an obscure feature of a particular implementation that no one really thought about but someone somewhere relies on in an important piece of code.

 Perl 6 Further Widens Language Use
Perl 6 will recognize and execute Perl 5 code, but it will also open new doors to developers with features including strong typing of data, provisions for metadata and a substantial cleanup of the language's distinctive pattern-matching capabilities.
With development releases of Perl 6 expected to emerge this year, and perhaps a production release by around this time next year, it's appropriate for developers to start familiarizing themselves with the benefits and the costs of Perl 6 adoption.
Perl 5.8 continues to be the main branch in active use, supported by a still-flowing stream of resources such as the mid-2005 fourth edition of O'Reilly Media's "Learning Perl" from authors Randal Schwartz, Tom Phoenix and Brian Foy.

 Amazon.com: Perl 6 Essentials: Books: Allison Randal,Dan Sugalski,Leopold Totsch   (Site not responding. Last check: 2007-10-20)
Perl 6 Essentials, which is intended to be reissued several times during Perl 6 development, aims to keep working Perl users informed of architectural decisions, feature additions, syntactic changes, and community developments as they occur.
As the authors state in the foreword "Because Perl 6 is rapidly changing, we'll publish a revised edition of the book every year until Perl 6 is released", this is a book about a snapshot of the current development of Perl 6.
If you want to get an overview about the status of the Perl 6 development and you want to support the development of Perl 6 (in the form of royalties for the authors that are working in Perl 6), you should buy this book.

 NewsFactor Network | Perl Features of the Future - Part 1
Perl is somewhat unique among programming languages, largely because its inventor, Larry Wall, wanted his creation to resemble a natural language.
Instead of trying to generate all the ideas for Perl 6 on his own, Wall asked the Perl community to submit Requests for Comment (RFCs) on suggestions for the language.
Perl 6 project manager Nat Torkington confirmed the scope of the planned revision, telling NewsFactor, "There will be substantial changes in the move from Perl 5 to Perl 6.

The reason Perl is used mostly for small programs is that the immune system kicks in if you overdose on it and although Perl looks like bat barf, most people will just stop coding before they actually Herl.
Perl was created to solve those problems that were caused by real and artificial stupidity -- file formats created by morons, log files that were almost completely useless, idiotic incompatibilities between programs, etc...
To enable these, Perl 5 introduced a feature called `references', and using references is the key to managing complicated, structured data in Perl.

 PERL - What is Perl-6?
The change from Perl4 to Perl5 was essentially Larry Wall's rewrite of Perl, and quite a bit was added to the Perl language at the time (but not much of the Perl4 language was changed).
Primarily, rewriting the core of perl (that's the perl source code, not the Perl language) will make it cleaner, faster, more extensible, easier for people to understand, and more accessible to other people who can then participate in the maintenance and development of perl itself.
You won't be required to do this sort of thing, but it allows perl to optimize the code if you do.
