Data.Parameterized.Pair

Description

This module defines a 2-tuple where both elements are parameterized over the same existentially quantified parameter.

Synopsis

Documentation

data Pair (a :: k -> *) (b :: k -> *) where Source #

Like a 2-tuple, but with an existentially quantified parameter that both of the elements share.

Constructors
