BTW, the main thing in that guide that I disagree with is the 4-space indentation. I always use 2, but at the top level there's a slight special case: foo :: a -> b foo x = bar x where bar y = ... We have to indent the body of the function here by 4 because the where has to be indented by 2, and the body has to be more than that, this is partly for clarity but also partly because of this problem: foo x = case x of This -> That -> where bar y = ... IIRC, historically in H98 this attached the where to the top level function foo, but these days with the modified layout rule, the where gets attached to the last branch of the case.
