Two exception types

Problem

Define two custom exception classes, TooSmall and TooBig, each inheriting from Exception, with message methods returning too small and too big respectively.

Loop over the two types and, for each, throw an exception of that type inside its own block. Use a CATCH phaser with a when branch for each type, printing small for TooSmall and big for TooBig. This way you see both branches get used.

Example

The program prints:

small
big
