>From my perspective, that's an unfortunate decision and I question the
rationale.  First, nonlocal doesn't behave exactly like global (you
cannot declare a previously undefined variable nonlocal as you can
with global).  Second, the PEP 3104 description explicitly mentions
that Guido favored adding this behavior to global; I would have
preferred that approach to not providing the extended assignment
support for nonlocal.  Third, I believe that it adds some clarity to
the code.  Seeing 'nonlocal x += 1' immediately tells me that I'm
incrementing a variable defined in an outer scope.  Having 'nonlocal
x' on one line and 'x += 1' on another makes it a little less clear.

But I do appreciate the reply!
