Fair question. On rethinking, I'm okay with an explicit check for None
or zero, ``if number is None or number < 0`` but I don't like the idea
of accepting *any* falsey value.
Calling the function with False is fine, since False == 0 but I don't
think it is fine to call the function with (say) [] or {} or "", which
are all falsey values.
