We all can pretty much guess that map, filter, and reduce will be 
reimplemented in a functional module by a third party within mere 
seconds of Python 3000 being released :-).  So it's really just a 
question of whether it will be let back in to the standard library as a 
module (rather than builtins) or not.  Even granting the reasons for 
removing them as builtins, I really can't understand the motivation for 
removing them entirely, not even as a standard library module.
