There's a new PEP proposing to change how to treat StopIteration
bubbling up out of a generator frame (not caused by a return from
the frame). The proposal is to replace such a StopIteration with a
RuntimeError (chained to the original StopIteration), so that only
*returning* from a generator (or falling off the end) causes the
iteration to terminate.
The PEP says """any generator that depends on an implicitly-raised
StopIteration to terminate it will have to be rewritten to either catch
that exception or use a for-loop"""
Shouldn't that be "... explicitly-raised ...", because returning raises
StopIteration implicitly? ("raise StopIteration" is explicit)
