4tH is a Forth compiler with a little difference. Instead of the standard Forth engine it features a conventional compiler. 4tH is a very small compiler that can create bytecode, C-embeddable bytecode, standalone executables, but also works fine as a scripting language. It supports about 95% of the ANS Forth CORE wordset and features conditional compilation, pipes, files, assertions, forward declarations, enumerations, structures, suspended execution, recursion, include files, etc. It comes with an RPN calculator, line editor, preprocessor, compiler, decompiler, C-source generator, a virtual machine, and a multitasking environment.

Red language is a native-code compiled functional, imperative, symbolic, and homoiconic programming language that re-uses most of REBOL's syntax and semantics. Both static and JIT compilation support are planned. A strong emphasis is made on concurrency and both task and data parallelism support using an actor-like abstraction and parallel collections (Scala-like). The target range of usage spreads from low-level system programming (thanks to the built-in Red/System C-level DSL) and embedded systems, up to high-level scripting, with an optional REPL console.
Mup produces very high quality PostScript printed music or a MIDI file from a text input file. It can handle almost any kind of music, instrumental or vocal, including tablature, shaped notes, guitar grids, alternate tunings, user-defined symbols, and much more. Mup has been under active development since 1992.
Ctalk adds classes, methods, operator overloading, inheritance, and complex object expressions to otherwise standard C programs. Programs can use only a few Ctalk objects and methods in an otherwise standard C program, but the language can be used to write entire programs also. Ctalk works on most if not all of the systems that support GCC, the GNU C compiler. The package includes the language, class and run-time libraries, example programs, tutorial, and language reference.
