[Sorry, this bounced -- my new work mail isn't set up right yet]
In the re-Module which come with Python version 2.0 (Nov 28 11:10 re.py) the created MatchObjects cannot be copied with a deepcopy(). Switching back to the old "pre.py" as proposed in "re.py" makes everything work ok.
thought I'd check this one with python-dev before marking it as "won't fix". I cannot see any reason why anyone would even attempt to deepcopy match objects...
(cannot see any reason why anyone would use deepcopy for anything, but that's another story)
Why don't you ask what they were doing? They cared enough to figure a workaround *and* report a bug. I think they deserve a better answer than Won't Fix.
