Python Parsers Comparison

[Randall Hopper]

I'm again faced with the "regexes not powerful enough for nested grammar"
problem, and need to chose an extension.

Does someone know of a web page or paper which compares the various Python
parser engines on a simple example grammar (or on features)?

For example, a comma-separated list of nested vectors would be a good example:

    [ 1, 2 ], [ 3, 4 ]
    [ [ 1,2 ],[ 3,4 ] ], [ 5.6 ]
    etc.

mxTextTools, metalanguage, SimpleParse, SPARK, YAPPS, PyLR, kwParsing,
PyBison.  A comparison of any subset would be useful.

Thanks,

Randall
