I suppose that's fine.  Also i guess

    nonlocal x = y = 0

seems okay.  We have to be clear that you can't assign to anything
that you could in a normal assignment though -- e.g.:

    nonlocal foo.bar, a[5] = 1, 2

is not allowed.

I've updated the PEP to allow multiple assignment and to specify
the exact grammar of the "nonlocal" statement.
