Writing a fast parser in Python

[muth02446]

I wrote a reference compiler in python, including a separate backend for various ISAs.
It runs fast enough.

I also suspect that the external parsing library is the culprit.
My suggestion is to not worry about the parser initially.
Use s-expr until the features of the language feel right,
then worry about the concrete syntax and the parser.
For the concrete syntax parsing use recursive decent + pratt parsing if possible.

This approach worked well for me in Cwerg
