Hello,

Python 2.7.8 and Python 3.4.2 (from Debian testing) have a different behavior on the attached file. Python 2 raises "bar", Python 3 raises "foo".

I can't find an adequate explanation in the documentation for this behavior difference. It probably relates to https://docs.python.org/3/reference/compound_stmts.html#try (search for "When an exception has been assigned") but this is unsatisfying because it only talks about the "as target" construction, which is not used in the example.

I think that at least the documentation should be clarified to point out what "raise" without arguments will do. Currently the documentation of this in Python 2 and 3 is the same even though the behavior is different https://docs.python.org/2/reference/simple_stmts.html#raise https://docs.python.org/3/reference/simple_stmts.html#raise.
