... but no more confusing than the fact that [f x | x <- xs] is
not the same as (map f xs).
Can you explain why? On page 258 of Paul Hudak's book "The Haskell School of
Expression" he states that do x<- xs; return (f x) is equivalent to [f x | x
<- xs] "which is clearly just map f xs"
I can't find anything wrong with the example in the book but perhaps I've
missed something?
