AFNIX is a multi-threaded functional writing system with dynamic symbol bindings that support the object oriented paradigm. It has a rich set of features providing runtime compatibility with C++. The engine runs on both 32- and 64-bit platforms, and it is designed to be portable across platforms.
Alice ML is a functional programming language that enriches the statically typed, closed functional world of ML with extensive support for type-safe programming of concurrent, distributed, and open systems. It also features cutting-edge constraint programming technology in the tradition of Oz/ Mozart. Alice ML is a mostly conservative extension of Standard ML.
Amber for Parrot is an object-oriented scripting language for the Parrot virtual machine. It combines the traditional advantages of scripting languages with support for software correctness and large-scale software engineering. Amber for Parrot has syntax and semantics somewhere between those of Eiffel and Ruby.
ACDK is a development framework with a similar target of Microsoft's .NET or Sun's ONE platform, but it uses C++ as a core implementation language. It implements the standard library packages, including acdk::lang, acdk::lang::reflect, acdk::util, acdk::io, acdk::text (including regexpr), acdk::net, acdk::sql, acdk::xml, and more. Flexible allocator/garbage collection, threading, and Unicode are implemented in the core of ACDK. Extensions make C++ objects available for reflection, serialization, aspect-oriented class attributes, and [D]ynamic [M] ethod [I]nvocation. This DMI acts as an universal object oriented call interface to connect C++ with scripting languages (Java, Perl, Tcl, Python, Lisp, Visual Basic, and VBScript) and standard component technologies (CORBA and COM).
