Hello everyone,
I am quite new to monadic code so I would like to ask for improvement
suggestions on the last line of the code below.
I know I could do something like do strs - mapM ...; intercalate ...
etc, but I would like to avoid the use of -.
Thank you,
José

First of all, return x `ap` y = x `fmap` y or x $ y. fmap (or its infix
synonym ($)) is the answer here, you could write:
someFn docs = concat . intersperse \n $
Try:
concat . intersperse \n $ (sequence $ map loop docs)
