The NSObject docs say that an init method might raise an exception. Is there some other init rule that I've missed, or have I just gotten lucky?
When in doubt, remember to look at the super-class documentation:
http://developer.apple.com/mac/library/documentation/cocoa/reference/Foundation/Classes/NSObject_Class/Reference/Reference.html#//apple_ref/doc/uid/20000050-init
All classes that inherit from NSObject (which means pretty much
all of them) inherit NSObject's –init method, and that's assumed
or implicit in the Array examples you referenced above . . .
