Try:
concat . intersperse "\n" <$> (sequence $ map loop docs)

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
data XmlState = XmlState Int type XmlM a = State XmlState a
loop :: Document -> XmlM String
someFn :: [Document] -> XmlM String someFn docs = return concat `ap` (sequence $ intersperse (return "\n") (map loop docs)) <--- improve this line
