These are good questions to which I do not have an answer :).  I don't
know how hard it would be to layer a TestRunner-compatible interface on
top of py.test tests, in particular; it may make sense to go with
something simpler.

I don't think it has to be compatible with nose or py.test -- they are
fast-moving frameworks compared to stdlib and they can adapt!  The
problem is to get something *into Python itself* so that we can have
standard ways of specifying these things.

Is it the job of unittest?  Dunno.  It should be in the stdlib IMO;
where else?
