From the disassembly it seems that the generator is a code object but

That's because x is not assigned to anywhere in the
body of foo. The bytecode compiler optimizes away the
creation of a cell in this ca

As I understand it, the object 'x' b

Your example with generator expressions is interesting.
Even more interesting is:
def foo(x):
y= (i for i in x)
return y
From the disassembly it seems that the generator is a code object but
'x' is not a cell variable. WTF?

Yeah, I know. It's the price we pay for forsaking variable declarations.
But for java programmers like me, Py's scoping is too complicated.
Please explain what constitutes a block/namespace, and how to refer to
variables outside of it.
