This needs more documentation than the typical patch.

I disagree. So far, nobody has spoken against the proposed feature. It's really a small addition of a new method to an existing type. Entire classes have been added to the standard library without a PEP. People can still criticize the patch when its posted (and it's not clear that the OP is even willing to produce a patch).

Agreed. Just implement it including test cases testing and demoing the corner cases. Making match objects have sequence and dict behaviour for groups is imnsho just common sense.
