Self-Hosted Python

Python continues to impress me with things like a C compiler written with Python. Building special purpose machines with tools like LLVM is beyond me. It’s one of those subjects that I seem to doze off reading. However, I have built a couple grammars with ANTLR. I just went to see what’s new with ANTLR and saw the ANTLRWorks GUI Development Environment. This would be a pretty good thing for PLY to have.

One could use Parrot to build a Python interpreter, or embed an interpreter in PHP, but I think I prefer RPython for my alternate implementation.
