Naturally. ;-) The discussion started here:

  http://www.haskell.org//pipermail/libraries/2005-February/003143.html

There were many different (but more or less equivalent)
versions of these combinators posted in the thread.

Not yet. I still plan to set up a Darcs repository for this
kind of thing ("prelude extensions" it is called on the
Wiki), but I may not get around to it for the next couple of
weeks, unfortunately. I've recently started working as
full-time a software developer (in C++, yuck), and ever
since my own private projects have come to a screeching
halt. It's very annoying. Anyway, I guess I'm not the only
one on this list who has that problem. ;-)
