Defines a logical operator that verifies the given parameter to extend TExtendee.
Defines true if TExtender is assignable to TExtendee, otherwise false.
remarks
It verifies that you may physically assign a value of type TExtender to TExtendee.
That's why union types with excess members that are not assignable to TExtendee
will evaluate to false.
