This looks pretty much like a no-brainer to me, assuming it stands up to
close scrutiny.  The only thing I'd change is that if PyDict_GetItem_Fast is
a macro that only works for interned strings, I'd change its name to reflect
its use: PyDict_GET_ITEM_INTERNED or something similar.

As a further test, I suggest you give the pystone benchmark a whirl, not
because it's such a kickass benchmark, but because it occasionally fiddles
global variable values.  I imagine it will do just fine and probably run a
bit faster to boot.
