  9. module Data.Singletons

    This module exports the basic definitions to use singletons. See also Prelude.Singletons from the singletons-base library, which re-exports this module alongside many singled definitions based on the Prelude. You may also want to read the original papers presenting this library, available at https://richarde.dev/papers/2012/singletons/paper.pdf and https://richarde.dev/papers/2014/promotion/promotion.pdf.

  10. module Control.Applicative.Singletons

    Defines the promoted and singled versions of the Applicative type class.
