You can of course say the same for all other types for which an implicit 'default'
is implemented. The more so because a class is initialized with 0 in which
case every enumerated and boolean will be ord(0) unless otherwise
initialized in the constructor.

So I don't see why this rule is not applied to all properties, I don't think
it is logical.
