That's debatable. Personally, I hate using NSEnumerator because it's 
slow. (Not only does it create an autoreleased enumerator object, but 
most of the standard collection enumerators copy the collections they 
enumerate over.)

On the other hand, using fast enumeration via the "for...in..." syntax 
in ObjC-2 is a total win. Not only is the syntax clear, but the 
implementation is very efficient (faster than -objectAtIndex, much 
faster than NSEnumerator.)
