I wouldn't necessarily expect it to be doable with regexps.  One of the
weirdest approaches I've ever seen is Emacs's mail-extr.el which IIRC
used a special major-mode and syntax tables to parse an address.

I would sort of expect that anything we include in the stdlib would do
support both the parsing and the validation use cases with as much
common code as possible.

This probably can't be done for Python 2.4/email 3.0 but lets put it on
the list for email 3.1 (which may have a different release schedule than
Python 2.5).
