All that means is that

   def g():
     try:
       if 0:
         yield
       return
     except StopIteration:
       print "Spam"

won't print "Spam". But since this involves catching the
exception with an explicit try-except, it doesn't fall
under the scope of your complaint.

I would put it the other way around -- the problem
that 'yield break' is meant to solve is already solved
by 'return'. So there's no need for change.
