==History==
Obliq is an interpreted domain specific programming language that is shipped with later versions of the Modula-3 System. It is intended to be used to program web "agents" (in a much wider understanding than agents are used in normal computer speak), in other words a utility programming language for the web rather than a scripting language of any sort and is in this reminiscent of '''WebL''' ([[Oberon]] variant).

Modula-3 is a systems programming language that descends from Mesa, Modula-2, Cedar, and Modula-2+. It adds objects and classes, exception handling, garbage collection, lightweight processes, and the isolation of unsafe features.

History

Originally developed by Acorn USA an operating system development tool and then called Modula-2+, it added multitasking, threading and multi programming features to the Modula-2 programming language, but M2 itself is a development of Pascal by its original author and adds separately compiled modules, stricter & clearer syntax and a host of system programming additions to Pascal in addition to a general clean up of the language features. Modula 3 is a development that adds memory management (garbage collection), type & generic safety features, generic programming, better exception handling and object-oriented extensions to Modula-2+. There is also an obscure variant called simply Modula-3* that adds strong parallel processing features to the language.
