Hi there. I'm a teacher of Maths and am working my way through the Euler
Project problems for fun. I have mostly been using Basic, but have read
up about Haskell and think it looks like a sensible way to solve many of
the problems.
OK, so I've downloaded GHCi and am trying to teach myself.
So far

This function works just as I want it to.
Now I try creating a list:
Prelude> [(a2+b2,a)| a <- [1..4] , b<- [1..4], a2+b2<20, b<=a]
[(2,1),(5,2),(8,2),(10,3),(13,3),(18,3),(17,4)]

It certainly is.
