Manuscript (Case [Issue]22671) _Inbox - IdentitySet>>asSet returns an IdentitySet instance instead of Set

Sven Van Caekenberghe edited Case 22671: IdentitySet>>asSet returns an IdentitySet instance instead of Set: Bug in  _Inbox: Not Spam  •  You are subscribed to this case I do not immediately see that there is a problem. In general #asXX methods do not guarantee a copy (self is returned in almost all cases when the message is received by a compatible class). A subclass is (or should be) compatible with its superclass, hence it is not necessary to return a Set or a String, a subtype is OK too. Consider '100 €' asString. which returns a WideString, not a String (which does not even exist as concrete type). Why exactly is #asSet returning an IdentitySet a problem for you ?
