Dang it.  Hit deliver too soon.   The whole point was also to say that  
these APIs are available in the 32 bit -- the legacy ObjC -- runtime,  
too.   You can write one bit of code that'll behave the same in 32 bit  
and 64 bit.

Convenient and consistent, but it doesn't make it any more of a good  
idea to go and class_replaceMethod() on just any method of any class. ;)
