How to get two values ​​from one, point, in Haskell?

Question

For example, if you set the value v and the function f , is there a way to get the (fv,v) point for free?

Answer 1

Alternatively, note that for functions h and f with the corresponding types

 h >>= f = \w -> f (hw) w 

so you can write

 f >>= (,) 

Answer 2

 import Control.Arrow (g &&& f) v = (gv, fv) -- ergo, (id &&& f) v = (v, fv) (f &&& id) v = (fv, v) 

Answer 3

How about using Applicative instance for (->)

 liftA2 (,) id :: (a -> b) -> a -> (a, b) 

for instance

 liftA2 (,) id succ 5 >>> (5,6)
