Excellent! Love it. Add that to the feature list for Python 2.8.

But for those of us still discussing the 3.x line, do we need to put
together a PEP about this? There seems to be a lot of bikeshedding, a
lot of broad support, and a small amount of "bah, don't need it, use
regex/long expression/etc". Who wants to champion the proposal? Do we
have a core dev who's interested in sponsoring it?
