That's a nasty code smell. Why would you want your code to behave
differently depending on what the text of the message is? The message
should not change the semantic meaning of the exception type.

If there are exceptions that *mean* different things (i.e. that require
different handling), they should be different types.

See the Python 3 standard exception hierarchy for a good example.
