Backwards function composition. This is a specialization of <&>, but it has a different fixity.

under :: (Newtype n o, Newtype n' o') => (o -> n) -> (n -> n') -> o -> o'

newtype Control.Newtype

A very simple operation involving running the function "under" the newtype. Suffers from the problems mentioned in the ala function's documentation.

under :: (Newtype n, Newtype n', o' ~ O n', o ~ O n) => (o -> n) -> (n -> n') -> o -> o'
