I see no need - if you're testing for "true" return values, bool is
correct. But if you're testing for None vs an actual value, it's not.

The fact that testing for boolean true values is a lot rarer than
people think, or that it's not appropriate in certain situations,
doesn't mean it's useless.

Paul.
