Interpreted, with 1 type (all is data) only, made with Java; can be used as strings of its own code or as Java objects, code (even 1-line program) can write or modify other code; main purpose: write artificial intelligences that modify (parts of) themselves or write other code.
Object-oriented extension to C language. Solves many of the problems associated with C++.
Project to create object-oriented language that is easy to learn for beginners.
Experimental, innovative, object-oriented, interpreted language, and programming environment LavaPE; edits programs via syntax-sensitive point-and-click style structure editors, not text editors; parameterized (virtual) types, refactoring, static checks.
OO language based on, integrated with, Java (compiler emits Java bytecode); features of functional programming, implements state-of-art results from academic research, for more expressivity, modularity, safety. [Open source, GPL]
Interactive geomatic object-oriented language for spatial modeling, image processing, remote sensing, digital photogrammetry, geographic information system (GIS), geodesy, and surveying and mapping.
Syntax similar to C++, Java, advanced high level features: strong type system, automatic memory management, global code optimization. Development website, has some documentation, forum, announcement from developers, sources. [Open source, GPL]
Full-featured, semi-dynamic object-oriented language. [Open source, GPL]
Compiled object-oriented language fully based on XML syntax; conforms to XML version 1.0 specification as published by W3C. Descriptions, documents, FAQ, downloads, links. [Open Source, LGPL]
UnrealScript Language Reference
High level, simple, Java-style, object-oriented, compile time error checking; native support for major concepts of time, state, properties, networking, which few languages address, to greatly simplify code. Mainly for games.
Language with objects, interfaces, parameterized types, no inheritance, operator overloading, generators, static instantiation, compiled to C; descriptions, source code, examples, compiler.
Ruby-like expressiveness + static type checks, like Haskell. [Open Source, GPL]
Practical OO language: Ruby-like expressiveness with Haskell-like static type checks. Coded in ML, runs on Linux. [Open Source, GPL]
