Or, he could have PyPy rewrite it for him:

If we continue on the track of maximum generality, we should be able to 
hook a C/C++ parser/code generator into the front end of PyPy. And with a 
flexible enough backend, instead of PyPy-Psyco emitting machine code or 
C, it should be able to emit Python code.

The trick is to write such a beast such that comments are preserved and 
the emitted python code is readable.
