In a comment to one of my answers, SO user sdcwc essentially pointed out that the following code:
comb 0 = [[]]
comb n =
let rest = comb (n-1)
in map ('0':) rest
++ map ('1':) rest
could be replaced by:
comb n = replicateM n "01"
which had me completely stunned.
Now I am looking for a tutorial, book or PDF that teaches these advanced concepts. I am not looking for a "what's a monad" tutorial aimed at beginners or online references explaining the type of replicateM
. I want to learn how to think in monads and use them effectively, monadic "patterns" if you will.
