You are making a big, unwarranted assumption about how
reverseObjectEnumerator works. Namely, you are assuming that it merely
tracks an index, and uses -objectAtIndex: (or equivalent) to retrieve
each object.
actually, there was an extensive thread last year. It seemed each
enumerator created surprisingly a copy of the array, giving the OP
some memory (or performance?) related trouble. IIRC it was the
combination of a tight loop with tons of enumerators w/o local
autorelease pools. Fast enumerators probably changed the rules since
Tiger.
