Except you don't need to do such a thing -- "yield" is much the same as
"print" this way. Both have the same effect on the stack frame: none. So
if you don't find print to be confusing wrt local state, you shouldn't find
yield confusing wrt local state either.
> Generators have to me always felt more "class-instance-like" than
I *exoect* you'll feel more the opposite the more you use them. Heck,
they're so much like functions that Guido reused "def" for them <wink>.
