However, in A.addChild, i.parent get's the first one (introduced by A), and in main, it gets the second one (J , which derived from I). The identity check then fails because the pointers aren't the same, even though it's the same object in question.why not make Ia == Ib into cast(Object)Ia == cast(Object)Ib ?Because he's talking about 'is', not '=='?
ok `s/==/is/` now?
