How does one write
fmap (fmap (*2)) xs
without parenthesis? (Using . and $ instead.)
fmap (fmap (*2)) xs flip fmap xs (fmap (*2)) flip fmap xs $ fmap (*2) flip fmap xs $ fmap (\x -> (*) x 2) flip fmap xs $ fmap (\x -> flip (*) 2 x) flip fmap xs $ fmap (flip (*) 2) flip fmap xs $ fmap $ flip (*) 2 -- Felipe.
