Let's discuss it here unless it looks like we need wider input. This is 
related to issue37292 (_xxsubinterpreters: Can't unpickle objects 
defined in __main__), yes?

With PEP499, "python -m foo" should have __name__=='__main__' and 
__spec__.name=='foo'. Were you thinking the __module__ should come from 
__spec__.name (and that the PEP should make that clear)?
