I thought that NSEnumerator was implemented in terms of fast enumeration "underneath" - the docs seem to imply that, as does the existence of __NSFastEnumerationEnumerator private class. It may be still slower than directly using the fast enumeration syntax, but isn't there some gain to be had? I have hundreds of these enumeration loops and I still need to support 10.4; I thought I was getting *some* benefit automagically from fast enumeration on 10.5+
Also, wouldn't methods such as -makeObjectsPerformSelector:withObject: and CFArrayApplyFunction(...) gain some benefit from fast enumeration? I use these a lot too.
