Geremy and the parser are correct - it *is* a set. It would only be a
dict if you changed the comma to a colon.

Hello Geremy,
The whole point is, is not supposed to be a set; a set literal would
end with "})". As you can see, there is no such construct in the
string.
It's just a dict inside parentheses. Somehow, the parser seems to
think it's a set.

I was somewhat surprised to discover that Python 3 no longer allows an
exception to be raised in an except clause (or rather that it reports it
as a separate exception that occurred during the handling of the first).
So the following code:
