I think opinions diverge on this. Some people would argue that you
must expect a user to enter invalid input, ergo: no exception.
A matter of taste.

However: when you decide on Integer(), make sure to rescue the
correct exception class, rescuing _all_ exceptions can be problematic
(it could e.g. mute exceptions caused by a typo in the code).
