Modula-3

One of the few languages out there designed as a systems language from the outset. 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.

Obliq

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).
