I see the ambiguity, but I find the above confusing, too, because it looks
like a boolean expression, which it is not. I'd rather change the syntax to
clearly separate the tuple of exception classes from the target:

"except" [expression ["to" target]] ":" suite

"to" is currently a comma. Don't expect that to happen, though.

By the way, I don't recall having seen expression containing exception
*instances*, and only learned that this is possible when I looked up the
try statement in the reference. Is this for string exceptions or has it an
application in newer code?

Obviously, if you have to ask :-)
