I believe that at this point (what the exception spec would be
allowed to be: identifier?, tuple?, any expression?) the syntax should
be identical to the statement syntax (i.e.: any expression).

Less special cases to remember.

For the same reason, I believe that tuple expressions
("except (ValueError, TypeError)") should be obligatorily
enclosed with parens as long as they are obligatorily enclosed
with parens in the statement syntax (i.e., probably till Python 3.13
:)).
