Simple examples of useful new idioms that this permits ?

BTW, I remember there exists a package for lisp, called
"screamer", that turns it in a backtracking non-deterministic
language in the style of prolog, through a device called
CPS (continuation-passing style) transformation. While
python lacks S-expressions and lisp-style macros that
allow this for lisp, continuations are clearly the key
component of this gimmick. It might be worth its while
to have a better look.

There is also Oz. http://www.mozart-oz.org/ - I've long
dreamt of a language with some of the semantics of Oz
and Python syntax and libs. continuations and uthreads
seem to bring python somewhat closer to Oz.
