	Parrot FAQ -
		Parrot is in the early phases of its implementation.
		Parrot has an odd license -- it currently uses the same license as Perl 5, which is the disjunction of the GNU GPL and the Artistic License, which can be written (ArtisticGPL) for short.
		Any library used by Parrot must be fast enough to have a fairly small performance impact, small enough to have little impact on core size, and flexible enough to handle the varying demands of Perl, Python, Tcl, Ruby, Scheme, and whatever else some clever or twisted hacker throws at Parrot.

	perl - Article and Reference from OnPedia.com
		Perl is a general-purpose programming language originally developed for text manipulation and now used for a wide range of tasks including system administration, web development, network programming, GUI development, and more.
		It is not possible, within the language, to leak memory, crash the interpreter, or corrupt its internal data representation.
		Critics argue that the language's support for different "dialects" and paradigms leads to "write-only" code, and that its easily-obfuscated mixture of sigils, special variables, and "Huffman encoded" shortcuts renders Perl code indistinguishable from "line noise".

	Parrot Diet -- Recommendations and Resources (Site not responding. Last check: 2007-10-29)
		The Paradise Parrot (''Psephotus pulcherrimus'') was an unusually colourful medium-sized parrot native to the grassy woodlands of the Queensland - New South Wales border area of Australia.
		Paradise Parrots lived in pairs or small family groups, making their nests in hollowed-out termite mounds and similar places, often at or near ground level, and feeding, so far as is known, almost exclusively on grass seeds.
		The plumage was extraordinarily colorful, even by parrot standards, a mixture of turquoise, aqua, scarlet, fl and brown, and the tail almost the same length as the body—something difficult to understand in a bird that, although a rapid, undulating flyer, spent almost all of its time on the ground.

	Vulturine Parrot -- Recommendations and Resources (Site not responding. Last check: 2007-10-29)
		Parrots have a characteristic curved beak shape with the upper mandible having slight mobility in the joint with the skull and a generally erect stance.
		Confusingly, the term "parrot" can be used in either the narrow sense of the parrot family Psittacidae or the broad sense of the order Psittaciformes.
		Other scholars claim that parrots are only repeating words with no idea of their meanings and point to Pepperberg's results as being nothing but an expression of operant conditioning.

	Squawks of the Parrot: Parrot Forth
		This project's actually coming along nicely--I've a compiler of sorts for the language that'll translate it into perl code, and we'll use that as a fallback plan if need be--and I should be able to start emitting PIR code (Parrot's intermediate representation, the stuff we feed into IMCC) with about a week's more work.
		I could use the language I'm writing the compiler for but, let's be honest, if it was good enough to write that sort of library code I wouldn't have to be writing a compiler to retarget the damn thing.
		Parrot's got a number of partial and full languages that compile to it, but throwing away the gag languages (besides, Befunge doesn't support Parrot's calling conventions) it's down to either a nice compiled Basic or Forth and, for a number of reasons, I chose Forth.

		Parrot is destined to be the Perl 6 Virtual Machine, the software CPU on which we will run Perl 6 bytecode.
		Parrot is still very much usable; we've already seen one mini-language emerge that compiles down to Parrot bytecode (more on that later) and Leon Brocard has been working on automatically converting Java bytecode to Parrot.
		Parrot is obviously developing very rapidly, and we still have a long way to go before we are ready for a compiler to this platform.

		Although Perl remains a vibrant language with a fiercely loyal following, it has undergone many changes to keep up with new technologies and applications that were not anticipated when Perl was first introduced in 1987.
		Parrot is the "Virtual Machine" or CPU that will run Perl 6 and other languages.
		Because Parrot is largely independent of Perl 6, a rather well understood subject and is needed as the basis for everything else, we can read most about this subject in "Perl 6 Essentials".

		Parrot is starting to become the Duke Nukem Forever of the VM world and a big Perl 6 uptake is unknown at this time.
		You can off course run other languages on it but that require a lot of difficult work to fit your type system into the Java one and the resulting classes might be strangely-formed.
		Parrot isn't in a usable state now and I wonder if it will ever be, but it's an interesting dream...

		This is not a design goal of the Parrot compiler tools, but it doesn't hurt to make it possible when the two layers of syntax tree are a design advantage anyway.
		It roughly corresponds to the constructs of a high-level language (such as Perl 6), but is generic enough to be useful in many different high-level languages.
		PAST is not a language, it's a tree of objects that represent the components of HLL constructs.

		Parrot is a virtual machine specification and implementation being written to run Perl 6.
		Supporting other languages on the Parrot VM is also a goal.
		There are no real languages running on Parrot, so you can't compare the standard implementation of language X to the Parrot version of language X. Instead it's simply stated that Parrot will be faster than existing language implementations, but proof-by-assertion isn't very convincing.

	Writing an interpreter, targeting a VM or writing from scratch? \| Lambda the Ultimate
		Parrot may have support for tailcalls; I'm not certain about this, but its erstwhile chief architect was a big fan of CPS and functional languages.
		Parrot does support tailcalls, but I believe that you have to mark tail-recursive capable subroutines for the VM to know to optimize them.
		Parrot also had the benefit of leveraging CPAN (well, once it's working with Perl 5 and 6), but the cross-language semantic issues are tricky, as I understand it.

	Parrot Assembly Language -
		Parrot's bytecode can be thought of as a form of machine language for a virtual super CISC machine.
		It makes sense, then, to define an assembly language for it for those people who may need to generate bytecode directly, rather than indirectly via the perl (or any other) language.
		Z has the function signature, which tells Parrot how to build the interface from parrot (and parrot's calling conventions) to the calling conventions of the library routine.

		In this model, Perl is parsed down to an abstract syntax tree and compiled into the Parrot assembly language bytecode.
		While all of this infrastructure is intended to support Perl 6, the intent behind Parrot is to keep it agnostic about a high-level language's constructs.
		As a result, plans are in the works for Parrot to interpret and transform other bytecode formats, such as the.NET Common Language Runtime (CLR) and the Java virtual machines (JVMs).
