Oops, I forgot to mention one other thing. This works but is excessively wordy and strange. In a class method, [self class] is equivalent to self. -isEqualTo: is a method that exists for AppleScript support; the proper one to use is -isEqual:. However, since class equality is always the same as object identity, you don't need to use a method at all, but can shorten it down to if(self == [BaseClass class]).
