Because you were lucky. :-) The way you used method overriding didn't lead to crashes. > > And as to note 2) "The contrary is, for me, completely illogical."

(And I know you know :-) Yes, but if the child method does not have the same signature than the parent method, you "break the contract". If B inherits A, that means that all B are A, and so B.Method(x, y, z) must be replaceable by A.Method(x, y, z) everywhere. > as you have said yourself in a comment > in issue 78 "And the check is not done too for a native class inheriting > another native class.
