Yhc/Pyhi

From HaskellWiki

Pyhi is a complete Yhc bytecode interpreter written in Python.

It is available from darcs and runs a 'Hello World' example. A large number of bytecodes are unimplemented so many programs won't run yet.

Interpreting a language using an interpreted language is slow and the current version is about 100 times slower than C, although this will likely get faster over time.
