I agree, but it seems something more is needed here.  I would like to
be able to parse something that isn't separated by whitespace, and I'd
like to be able to tell Python to turn it into an int if I need to.
We could keep a similar syntax to the 3.0 formatting syntax, and just
change the semantics:

""First, thou shalt count to {n!i}" (or {n!d}) could parse an integer
out of the string, and "{!x:[0-9A-Fa-f]*}" + (":{!x:[0-9A-Fa-f]*}" *
7) could be used to parse MAC addresses into a list of 8 hex values.

I could easily see this getting way too complex, so maybe you all
should just ignore me.
