[Python-Dev] deprecated regex used by un-deprecated modules

[Jeremy Hylton]

There are several modules in the standard library that use the regex
module.  When they are imported, they print a warning about using a
deprecated module.  I think this is bad form.  Either the modules that
depend on regex should by updated to use re or they should be
deprecated themselves.  

I discovered the following offenders:
asynchat
knee
poplib
reconvert

I would suggest fixing asynchat and poplib and deprecating knee.  The
reconvert module may be a special case.
