Useful operators for defining functions in an applicative context

## Synopsis

- (%) :: (a -> b) -> a -> b
- (×) :: (a -> b) -> a -> b
- (<*<) :: Applicative f => f (b -> c) -> f (a -> b) -> f (a -> c)
- (>*>) :: Applicative f => f (a -> b) -> f (b -> c) -> f (a -> c)
- (<$<) :: Functor f => (b -> c) -> f (a -> b) -> f (a -> c)
- (>$>) :: Functor f => f (a -> b) -> (b -> c) -> f (a -> c)

# Documentation

(%) :: (a -> b) -> a -> b infixr 5 Source #

This operator is an alternative for `$`

with a higher precedence. It is
suitable for usage within applicative style code without the need to add
parenthesis.

(×) :: (a -> b) -> a -> b infixr 5 Source #

Deprecated: use `%`

instead

This operator is a UTF-8 version of `%`

which is an alternative for `$`

with a higher precedence. It is suitable for usage within applicative style
code without the need to add parenthesis.

The hex value of the UTF-8 character × is 0x00d7.

In VIM type: `Ctrl-V u 00d7`

You may also define a key binding by adding something like the following line to your vim configuration file:

iabbrev <buffer> >< ×

(<*<) :: Applicative f => f (b -> c) -> f (a -> b) -> f (a -> c) infixr 4 Source #

Functional composition for applicative functors.

(>*>) :: Applicative f => f (a -> b) -> f (b -> c) -> f (a -> c) infixr 4 Source #

Functional composition for applicative functors with its arguments flipped.
