So, it's quite possible that he has a "hash" used by the NSMutableSet which doesn't depend on the contents of the mutable dictionary once it's been created. Still, though I can imagine someone wanting such a set-up, I have to wonder what purpose it serves, as opposed, e.g., to a mutable dictionary of dictionaries, or a mutable array of dictionaries. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
