  CLU (programming language) - Wikipedia, the free encyclopedia
CLU is a programming language created at MIT by Barbara Liskov and her students between 1974 and 1975.
CLU and Alphard both seem to get as close as possible to being a full OO language without actually being one.
All objects in a CLU program live in the heap, and memory management is automatic.

With its emphasis on program safety, it is not surprising that Ada is a strongly typed language: all data elements must be declared as storing a particular type or subtype, and type enforcement is strictly applied both within and between modules.
CLU supported a number of advanced features for structured languages for its day, including garbage collection, a form of inheritance, iterators, strong typing, generics, and exception handling.
The basic view of programming exhibited by Escher and related languages is the a program is a representation of a theory in some logic framework, and the program's execution (computation) is a deduction from the theory.

 Exception handling Summary
Exception handling is a programming language construct or computer hardware mechanism designed to handle the occurrence of some condition that changes the normal flow of execution.
In those languages, the advent of an exception (more precisely, an exception handled by the language) unwinds the stack of function calls until an exception handler is found.
In those languages or environments the advent of a condition (a "generalisation of an error" according to Kent Pitman) implies a function call, and only late in the exception handler the decision to unwind the stack may be taken.

 CLU from FOLDOC   (Site not responding. Last check: 2007-11-03)
CLU is an object-oriented language of the Pascal family designed to support data abstraction, similar to Alphard.
It introduced the iterator: a coroutine yielding the elements of a data object, to be used as the sequence of values in a for loop.
A CLU program consists of separately compilable procedures, clusters and iterators, no nesting.

CLU was primarily developed as a tool to build Abstract Data Types using modules (aka clusters) and was highly influential in the development of programming languages.
Many of the features of CLU were novel; in addition to the support for data abstraction through clusters, there are iterators, the exception mechanism, and the mechanism for polymetric polymorphism.
Among the languages influenced by CLU are Ada, C++, ML, Modula 3, and Trellis/Owl.

 Lambda the Ultimate history
If you haven't read the paper, but studied programming languages, perhaps that easiest way to describe the paper is to say that it is the origin of the EOPL approach: Language understanding by building (applicative) interpreters.
The design of a language for the DoD mimicked the design of a software system: a list of requirements was agreed on (more on that later), and then several candidates were evaluated.
This paper is an interesting excursion into programming language archeology, a retrospective of a problem that the Y2K people faced, the 500 language problem, namely the reality that you have to write parsers for the 500 to 700 different languages that exist in the world before you can do semantic transformations on them.

In An Overview of Ada, Ada is presented as a programming language of the "second revolution" i.e.
CLU's cluster and Ada's package both have the same function: allowing to separate a data abstraction from its implementation.
I have no idea of the way CLU was designed but Ada is clearly a rational effort to study the programming languages of this period and finally to produce a new standard at least for military purposes.

If the programmer of a rule based system is not content with the default facilities of the programming environment he may define his own abstract data types that implement the working memories, the working memory elements, the rule sets, the conflict resolution, and/or the inference engine.
The XE language is a newly developed general purpose programming language that supports data abstraction and rule based programming.
The CLU programming language was used as a basis in the design, but XE is not an extension of CLU.

 The Sather Language: Efficient, Interactive, Object-Oriented Programming   (Site not responding. Last check: 2007-11-03)
One way of placing it in the "space of languages" is to say that it aims to be as efficient as C, C++, or Fortran, as elegant and safe as Eiffel or CLU, and to support interactive programming and higher-order functions as well as Common Lisp, Scheme, or Smalltalk.
In languages which do not separate abstract types from particular implementations, you are either forced to make all descendants implement routines which don't make sense for them or to leave out functionality in parent classes.
Because the compiler uses C as an intermediate language, the quality of the executable code depends on the match of the C code templates used by the Sather compiler to the optimizations employed by the C compiler.

 “Stretch” Languages, or, 28 years of programming at Oliver Steele
I use four kinds of languages: utility languages, for writing tools and solving problems; application languages, for writing distributable integrated applications; system programming languages, for implementing operating systems and low-level libraries; and a fourth category of languages, which I’ll call “stretch languages”, for learning how to program.
A stretch language can make it difficult to do even simple things, because I’m still learning the concepts that are necessary to use it idiomatically or, sometimes, to use it at all.
Some of the languages that aren’t in my list would be perfectly respectable stretch languages for someone else — I just happened to be familiar with their concepts by the time I got to them.

In many occasions you can replace a method pointer parameter with a CLU iterator call where the method call or the method itself is placed in the iterator loop body - all local variables are visible there, so there is no need to copy them temporarily to the object and afterwards back.
There are many applications where a CLU iterator is the method of choice...
CLU iterators are often not replaceable by for..in whereas vice versa always succeeds.

On the other hand, this separation is easier to achieve in languages from the Pascal family, but most of their encapsulation techniques were developed for the structured programming style.
The syntax for defining an iterator in Freya is inspired by the CLU programming language.
C#, Java and Delphi are mainstream programming languages that use interface types, but up to this date, they doesn't support assertions (rumor has it that a future CLR version could offer explicit support for assertions).

You must implement your project using the C programming language, and you must work within your team.
You should use these to help you decide whether your program is working correctly or not, based on what type of output your program produces out of these test input files.
Hence, a program might pass all the tests in these test files, and yet fail some of the extra tests used for grading.
