Since Python Version 2.5 it behaves the following:
1. pop yield value from stack and return it to
a former gen_send_ex() call from Objects/genobject.c
2. push the yield value on the stack in gen_send_ex() and return
Are you sure about that? I would expect the value pushed to
be the one sent back into the generator using a send() call
if any, or None if the generator is resumed using next()
rather than send().
3. when the generator is executed again, the yield value is
'poped' from the stack again with the POP_TOP opcode
This will happen if the result of the yield expression is
not used for anything in the Python code.
