A cursory examination of the pointers to this list in

Would it be possible for the list re-mailer to set the 'Reply-to:'
field to point to the list? Further apologies if t

My belief is that this is a mistake - it's the wrong way round - the

Thank you for pointing me to the System library. However, while I was
indeed implying that there is no way of returning an exit code, my main
question was which type main should have. You seem not to like IO Int
(one even for several reasons ;-) but it still looks quite natural to me.

Reasonable request.

This might be very easy, but I can't figure it:
I need the length of a list and it should be of type Integer, while the
prelude function yields type Int.
Is there a more clever way to get the result of the right type than just
adding a new version of length, namely:
lengthInteger::[a]->Integer

This looks like a bug in the prelude to me. It's not inconceivable
that in some implementation it might be possible to have a list with
length greater th
