They might be unique, they might not.
If I make two identical string constants
(@"samestring" and @"samestring") in my Cocoa program,
are their pointers guaranteed to be equal? I assumed
this without thinking while prototyping root objects
in an NSOutline view and it did work, however I just
realized that perhaps I shouldn't rely on th
