The current code would use try...except. Would that catch a KeyError
from inside f(y)? Yes.

The problem is that sometimes you want to catch only ZeroDivisionError,
so we need to be able to specify the exception.

The question is whether it should be OK to allow a bare except, where
that would catch a limited number of exceptions, in those cases where
there won't be any risk.
