Ackermann's function

[Wayne Young]

Greets,

    Sorry to intrude (new to both the list and to Haskell).

    I'm still getting the syntax correct (playing with simple functions,
etc) and was wondering how I would define Ackermann's function in
Haskell.  I'm curious to see how Haskell (using Hugs) will outperform C
and Pascal for this beast.

Thanks,
    W.Young
