I am surprised this is not already the behaviour of an Enum class,
without overriding the ‘__bool__’ method.
What would be a good reason not to have this behaviour by default for
‘Enum.__bool__’? (i.e. if this were reported as a bug on the ‘enum.Enum’
implementation, what would be good reasons not to fix it?)
