Jeff - 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. -- Paul -- http://mail.python.org/mailman/listinfo/python-list
