Earlier quoted context omitted.

Think of Pypy as somewhat like LLVM, except the language it's built on is a subset of the python language, called RPython. Although the most well-known language implemented in the pypy "vm" is python, the toolchain is completely language agnostic. So, this is more akin to Apple writing a C interpreter on top of llvm than it is to building a ruby interpreter on top of python.

PyPy is totally not like LLVM in many regards. It targets a very different demographics. Some differences: * RPython comes with a good garbage collector * the language where you specify what's going on is RPython in which you write an interpreter. Then you get a JIT using a few hints. This is difference than "interpreter in C + compiler to LLVM" scenario by quite a bit. * RPython comes with a set of data structures t…

Completely unscientific, but if these outputs are any indication, this is going to be great news for Rubby users in the future... $ time ruby -e "puts 'hello world'" hello world real 0m0.184s user 0m0.079s sys 0m0.092s $ time ~/Downloads/topaz/bin/topaz -e "puts 'hello world'" hello world real 0m0.007s user 0m0.002s sys 0m0.004s

So Ruby on top of RPython on top of PyPy? Why not, but how does it compare to JRuby and Rubinius?
