Amen!

I was waiting for somebody to say that...

There are a dozen situations in an imperative language where you'd write 
a loop. But in Haskell, you might well do something entirely different 
for each situation. So it really pays to focus on what the end result 
you're after is, rather than how to translate imperative code 
line-for-line into Haskell.
