 Back in August 2016, David Feuer
 [https://mail.haskell.org/pipermail/libraries/2016-August/027293.html
 proposed] adding this function (originally from `lens`) to `Data.Functor`:

 {{{#!hs
 (<&>) :: Functor f => f a -> (a -> b) -> f b
 as <&> f = f <$> as
 infixl 1 <&>
 }}}

 The proposal was well received, so let's implement it.
