Right. A class is an instance of its meta-class and class-methods are 
in fact normal methods of the meta-class (the meta-class itself is an 
instance of NSObject if you compile a normal Objective-C class 
definitions; it is of course possible to let the meta-class be an 
instance of another class if you define the class in C). You normally 
don't notice the existence of the metaclass, unless you start to do 
lowlevel hacking.
