Re: initializers in Categories?

I do this quite a bit in my code.  However, I have experienced one 
issue.

I attempted to create a initWithDescriptor: method for NSArray (at 
least I think it was NSArray).  The idea being that I could create an 
array from an NSAppleEventDescriptor.  However, when you send the 
initWithDescriptor: message, NSArray complains bitterly and 
effectively crashes the app.  It seems you cannot send any messages 
to an NSArray until you have used one of its init method.

In the end to solve this I just made a +arrayWithDescriptor method 
instead.
