Just to add to David's answer, when I find myself in situations like:
foo >>= return . bar
hlint helpfully suggests:
fmap bar foo
So you could also have:
fmap (splitOn ",") $ readFile "data.txt"

I now, of course, feel silly because <$> is the infix version of fmap;
apologies for list-spamming.

Personally I prefer <$> (infix fmap) to fmap, but is this confusing to
beginners?
