Part of the problem that was addressed in the previous thread was that +array is not documented to actually give you a mutable instance. While in practice it works fine, there's no guarantee.
Isn't guaranteed by the semantics of inheritance? I've specified the class: [NSMutableArray ... and what I want it to give me... array]; And the fact that NSMutableArray inherits NSArray ensures that anything that array can do, NSMutableArray can do.
