McCarthy
[21-Feb-2006,
Beta]

McCarthy is a simple, first-order functional programming language. The interpreter of this language is also called McCarthy. McCarthy is Turing-complete i.e. it can compute all Turing-computable functions on the integers. It is not suitable for general purpose programming as it offers only an elementary subset of the features found in general purpose programming languages, but it can serve as a model of computation.
Nnjoy
[07-Nov-2005, version
0.2,
Beta]
NJoy is a variant of the concatenative programming language Joy The main difference is that it is enriched with an easy to module system with optionally private declarations.
Only a part of the standard library of Joy is implemented. The interpreter is easy to use, but the builtin functions are poorly documented. The performance of the interpreter (natively compiled and stack traceback switched off) is on par with optimized C implementation of Joy.
