Ugh :-)
But...
What if break were implemented with an exception, like StopIteration but 
for interruption instead of stop? And for-loops were an implied 
try/except:
 for ...
 except BrokenIteration: # <-- implied
 pass
and you could go:
 for ...
 except BrokenIteration:
 ... a break occurred
 else:
 ... a break did not occur
and, indeed,
 for ...
 except BrokenIteration:
 ... a break occurred
 except StopIteration as stopped:
 print("I did", stopped.count, "iterations")
 else:
 # not reached because of the "except StopIteration" above
 ... a break did not occur
if we wanted to cover off the count iterations wish item.
