Orc is a library and set of tools for compiling and executing very simple programs that operate on arrays of data. The "language" is a generic assembly language that represents many of the features available in SIMD architectures, including saturated addition and subtraction, and many arithmetic operations.
Larceny is a simple and efficient implementation of the Scheme programming language. Created originally as a test vehicle for research on garbage collection and compiler optimizations, Larceny has grown into a major multi-platform system, and is one of the very few implementations that support all four de facto standards for Scheme: IEEE/ANSI, R5RS, ERR5RS, and the R6RS. Development of Larceny has been supported by NSF, Sun Microsystems, and Microsoft.
The GNU Modula-2 compiler is one of a number of front end languages to GCC (the GNU Compiler Collection). As such, it has been designed to coexist with other GCC languages. For example, it can be used in mixed language projects and it can catch C++ exceptions and throw exceptions which can be caught by C++. Users can also exploit conditional compilation and full gcc backend optimization and architecture coverage. GNU Modula-2 can produce position independent code and can easily produce shared libraries from modules. The compiler provides a swig interface file generator option, which allows scripting languages such as Python to import modules written in Modula-2 and also catch exceptions thrown by Modula-2. The compiler translates PIM2, PIM3, PIM4, and ISO dialects of Modula-2.
FeatureC++ is a C++ language extension that supports Feature-Oriented Programming (FOP). FOP studies feature modularity in program families. The idea of FOP is to build software by composing features. Features are basic building blocks that satisfy intuitive user-formulated requirements on the software system. Features refine other features incrementally. This step-wise refinement leads to a layered stack of features. Mixin Layers are one appropriate technique for implementing features.
