[Python-Dev] sre.py backward compatibility and PEP 291

[Barry Warsaw]

PEP 291 says that sre.py needs to be backward compatible with Python
2.1.  sre.py says:

# this module works under 1.5.2 and later.  don't use string methods
import string

Which is it?  Raymond has seen some circular reference problems between
my PEP 292 string.py patch and re.py (really, by way of sre.py and
friends).  Even though I haven't seen the same problems, I'd like to
avoid any direct circular references by changing the few string module
function calls in sre*.py to string methods.  But the comment above
stopped me, until I read PEP 291.

The PEP should be the definitive answer, and I'm willing to
string-meth-ify sre*.py, if there are no objections.
