Sorry not to reply sooner, I have been out of town with limited access to
c.l.py. Also, I didn't really pick up on "cPickle problems" as a
pyparsing-related post. :)
I would be happy to make ParseResults picklable, I didn't realize that this
getattr behavior was defeating that capability. I have had people
successfully use pickle on pyparsing grammars, but have not had anyone
report any pickle experience with ParseResults objects, either pro or con.
I have a test version of pyparsing with pickling support added, and it
passes my simple unit tests. I could send it to you if you would test it
against your program.
