Summary: MatchObjects not deepcopy()able

Initial Comment:

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.

I'm not sure this is a bug -- imo, you're relying on
an implementation artifact in the original PCRE port.
And making this work under SRE isn't as easy as it may
appear (the proposed patch may work in your specific
case, but it isn't a general solution).

But before I make up my mind here, maybe you could tell
me why you think it's a good idea to use deepcopy on
match objects.  Why not just store "m.groups()" or
"m.regs" instead?

Cheers /F
