Overriding methods

A subclass may override methods of its superclass. If it chooses not to, the superclass method is used. Correct?

So, NSMutableArray is a subclass of NSObject and inherits -init.

But when I use [ [ NSMutableArray alloc ] init ] I get no error message like:
"Please use initWithCapacity:", and it almost works - but only almost.

Should not NSMutableArray either override the inherited init-method in a documented way (e.g. with initWithCapacity: 0), or create an error message and have the non-usability of this method documented?

Same with NSButtonCell setBezelStyle and its superclass NSActionCell setBezeled.

Generally: should not the documentation clearly state (when not totally obvious) the function of inherited methods?

Gerriet.
