Which isn't available in pure Python anywhere, and isn't extensible 
enough to do what he wants to do.

Universal newlines doesn't really make sense in the context of unicode. 
  Unicode would definitely have another implementation, anyway 
(unicode.splitlines(...)).

FWIW, I've wanted to do things like this before..  but I think that the 
universal newlines support in fileobject should just be refactored so 
that you can use it without a file object (possibly with a similar API 
to this).
