Thats slow i have a parser that parses 100k in less then 15 ms on a
1,2 GHz system. It will be part of "http://www.python-ide.com"
It is a 100% GNU Eiffel solution which generates plain C code.

I think the 1/2 second could also be done with some intelligent
regexpr's. There is something like this in the IDLE code.
