> I wish something similar could be developed for Ruby. There's something like Pypy for Ruby already: It is Pypy itself. Pypy is a framework for implementing jitted dynamic languages (any language, not just python). You can generate interpreters for any language you want, as long as you write them in Rpython (restricted python). So, if you want a pypy for Ruby, just write a ruby interpreter in Rpython, and then use the pypy translation toolchain to compile it down to C, while automatically generating a just in time compiler for free.
