OK.  

It's a bit of a namespace collision actually (between Python usage and the
wider world), as there's a popular notion of a "reverse phone directory"
wherein you lookup names by phone number instead of phone number by name
e.g. http://www.reversephonedirectory.com/ (just found myself by number).

So is 2.4 mylist.reversed() something that returns a list, vs. reverses it
in place?  Is there a parallel mylist.sorted()?
