My understanding (and I could be wrong) is the as well as handling
memory allocation and deallocation any base class in Objecive-C also
has to handle some interaction with the runtime system for the class to
be useable (don't ask me what) if you tried to create your own base
class you would have to implement all of that yourself. There is no
reason your descendent class can't have an init method you will just
have to make sure that you NSNumber is initialized by some other means
other than by message forwarding.

Going about my only idea for finding this memory leak (as mentioned in
NSZombie, the other thread I just started), I'm implementing a class
that pretends to be an NSNumber.
I figured that I should subclass from NSProxy. Then I looked at
NSProxy and realized that it gave me no features at all, and as far as
I can tell just makes my life interesting by selectively not
implementing a few things; -init for example. So... what's the point
of subclassing NSProxy? What DOES it give you, aside from bookkeeping?
