Modula-3 is a systems programming language that descends from Mesa, Modula-2, Cedar, and Modula-2+. It also resembles its cousins Oberon, Object Pascal, and Euclid. Modula-3 retains one of Modula-2's most successful features, the provision of explicit interfaces between modules. It adds objects and classes, exception handling, garbage collection, lightweight processes (or threads), and the isolation of unsafe features. This is the Critical Mass implementation.

Parrot 是一个虚拟机，旨在有效地编译和执行字节码的动态语言。 Parrot 目前拥有各种语言的不同程度的实现，包括 Tcl、Javascript、Ruby、Lua、 Scheme、PHP、Python、Perl 6、APL、和一个 .NET 字节码翻译器。

BeanShell is a small, free, embeddable Java source interpreter with object scripting language features, written in Java. BeanShell dynamically executes standard Java syntax and extends it with common scripting conveniences such as loose types, commands, and method closures like those in Perl and JavaScript.

PHP, which stands for "PHP: Hypertext Preprocessor" is a widely-used Open Source general-purpose scripting language that is especially suited for Web development and can be embedded into HTML. Its syntax draws upon C, Java, and Perl, and is easy to learn. The main goal of the language is to allow web developers to write dynamically generated webpages quickly, but you can do much more with PHP.

Erlang is a programming language used to build massively scalable soft real-time systems with requirements on high availability. Some of its uses are in telecoms, banking, e-commerce, computer telephony and instant messaging. Erlang's runtime system has built-in support for concurrency, distribution and fault tolerance. This port contains a standalone runtime environment of Erlang 18 to be used during the development of OTP applications.

"Dive Into Python" is a Python tutorial for experienced programmers. The book is published under the GNU Free Documentation License and is available in a variety of formats. It is currently being translated into a number of languages.

The Cython language makes writing C extensions for the Python language as easy as Python itself. Cython is a source code translator based on the well-known Pyrex, but supports more cutting edge functionality and optimizations. The Cython language is very close to the Python language (and most Python code is also valid Cython code), but Cython additionally supports calling C functions and declaring C types on variables and class attributes. This allows the compiler to generate very efficient C code from Cython code. This makes Cython the ideal language for writing glue code for external C libraries, and for fast C modules that speed up the execution of Python code.

J is a modern, array oriented, high level, high performance, general purpose programming language. J is used in a variety of industries including banking, investment analysis, insurance, derivative trading, scientific research, and education.

Lua is a programming language originally designed for extending applications, but also frequently used as a general-purpose, stand-alone language. Lua combines simple procedural syntax (similar to Pascal) with powerful data description constructs based on associative arrays and extensible semantics. Lua is dynamically typed, interpreted from bytecodes, and has automatic memory management with garbage collection, making it ideal for configuration, scripting, and rapid prototyping. A fundamental concept in the design of Lua is to provide meta-mechanisms for implementing features, instead of providing a host of features directly in the language. For example, although Lua is not a pure object-oriented language, it does provide meta-mechanisms for implementing classes and inheritance. Lua's meta-mechanisms bring an economy of concepts and keep the language small, while allowing the semantics to be extended in unconventional ways. Extensible semantics is a distinguishing feature of Lua. Lua is implemented as a small library of C functions, written in ANSI C, and compiles unmodified in all known platforms. The implementation goals are simplicity, efficiency, portability, and low embedding cost.
