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?  How do I disassemble the generator?
Must look into this....

bytecode ]
