Simon Marlow pointed me to mail-archive.com.  For some reason Google
doesn't seem to index this site, and it's not an easy site to navigate

However, you can find the monadzero thread mostly on this page:
(search for MonadZero)

| | What do people think of the following proposal? Remove fail from the
| | Monad class. Reinstate MonadZero as a separate class as in Haskell
| | 1.4.
| This was debated extensively during the Haskell 98 process.  I'm not
| saying that we made the right decision then, but here's a link to (a
| part of) the discussion.

|  I'm hoping someone has an archive of the whole mailing list they can
| let us have (see my other message)
