Hi all, I'm probably in serious trouble here (i.e. I'm toying with things I don't understand); I have some code that I was using like follows, context removed for clarity: anotherFunc :: Int -> String ... map ((++) <$> show <*> anotherFunc) [1..20] This works great - the integers 1..20 are passed to each function and the results are catenated together. What if I'd like to add a third function? So far, the only workable solution I've been able to come up with is this: map ((++) <$> ((++) <$> show <*> anotherFunc) <*> yetAnotherFunc) [1..20] That's one unfortunate expression. I've been messing around with concat (trying to get the results of the functions into a list when all is well and done for concat to finally string together?), but all in all, have not had much luck with seeding the values in that way. I think there is probably an obvious solution I've missed... and hold on a minute! map (mconcat [show, anotherFunc, yetAnotherFunc]) [1..20] I just stumbled upon this. While I'm not 100% confident on what's just happened here, I thought I'd mail this out for everyone to enjoy the learning process that has been this email. This serves as a helpful pointer for me to study both monoids and applicative functors in depth, as the former suddenly leapt out of the recesses of my mind somewhere and solved it. Thanks for listening, and nice to meet you all! Cheers, Arlen
