[Hugs] elem of infinite set of tuple

[Neil Mitchell]

Hi

This is not the right emailing list for this - its not a bug in Hugs,
just the way Haskell works. I recommend you resend this email to
haskell-cafe -AT- haskell.org - that is a more general list and people
will be happy to help, plus you'll reach a much bigger audience.

Alternatively, hop on to IRC: http://www.haskell.org/haskellwiki/IRC_channel

There people will be happy to answer your questions in real time :)

Thanks

Neil
