Re: How to enable "shorthand" access element in NSArray

[David Chisnall]

Are you targeting the non-fragile ABI?  This array accessor notation is a 
terrible idea, so I'd recommend that you avoid it, as it (along with the 
property notation) destroy one of the key strengths of Objective-C: the 
orthogonality of syntax.  In particular, with the fragile ABI, you were allowed 
to allocate C arrays of objects, so myArray[1] means *(&myArray + 1).  It looks 
like that's what you're getting here, because the result of this will be an 
NSArray (not an NSArray*), which is incompatible with an id.

And are you sure that you're using clang?  That looks very much like a GCC 
error...
