Not sure what you mean here. Something like this?
def gen():
yield stuff
yield more stuff
for stuff in gen():
bomb with exception
The error didn't happen in the generator, so I wouldn't expect to see
it in the traceback. There's still room for the cause of an error to
not be in the traceback; imagine, for instance, a function that
populates a concrete list, and then you iterate over the list. If that
function sticks a None into the list and the subsequent processing is
expecting all strings, that's going to bomb, but then you have to
figure out where the None came from. If the traceback could include
that, it'd be great, but some things aren't possible. Doesn't mean
we're happy to sacrifice other functionality.
