When I did code profiling, the number of ObjC runtime calls went down,
without a corresponding increase in CoreFoundation.  My assumption is that
this would lower the total time a bit, but I¹ve not gone back and confirmed
that.  This looks like a great chance to test that, because I agree that the
readability of the later is much better.

Maybe I¹ll have info on that by tomorrow....
