The Caml Hump: Nnjoy

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.
