Thanks, Guido, Pablo, Lysandros, that's a great PEP. Also thanks to
everyone else working on the PEG parser over the last year, like Emily. I
know it's a lot of work but as someone who's intimately aware of the
headaches caused by the LL(1) parser, I greatly appreciate it :).
The only thing I'm missing from the PEP is more detail about how the
cross-language nature of the parser actions are handled. The example covers
just C, and the description of the actions says they're C expressions. The
only mention of Python code generation is for alternatives without actions.
Is the intent that the actions are cross-language, or translated to Python
somehow, or is the support for generating a Python-based parser merely for
debugging, as that action suggests?
