I don't think that's all that big of a deal even though I will readily
admit having stumbled on it early on. I removed the last "yield"
statement from a generator expecting it to keep on being a generator.
Thus, you have to do things like:

   def nothing():
       if False:
           yield None

The "pass" and "global" statements make me think it might be more
Pythonic to have separate syntax for the special case:

   def nothing():
       yield not
