FWIW, I expect the implementation will *allow* "raise exc from
Ellipsis" as an odd synonym for "raise exc".
Are we sure we want that? Raising from something not an exception seems
counter-intuitive (None being the obvious exception).
It isn't so much a matter of wanting it as "Is it problematic enough
to put any effort into preventing it?" (since allowing it is a natural
outcome of the obvious implementation).
I would say yes we want that. It would be strange if you couldn't
reset a variable explicitly to its default value. I don't expect
people to do this often. But somebody might want to do a deep copy of
an exception (with some systematic change), or there might be other
reasons. I'm sure a few Python zen items apply here. :-)
Okey-doke, I'll get it going.
