Functions

$>

$> : Functor f => f a -> b -> f b
Replace all locations in the input (on the left) with the given value (on the right).

<&>

<&> : Functor f => f a -> (a -> b) -> f b
Map a function over a functor. Given a value as and a function f, as <&> f is f <$> as. That is, <&> is like <$> but the arguments are in reverse order.

<$$>

<$$> : (Functor f, Functor g) => (a -> b) -> g (f a) -> g (f b)
Nested <$>.

void

void : Functor f => f a -> f ()
Replace all the locations in the input with ().
