Branch: CURRENT, Version: 5.2.5nb4, Package name: hs-kan-extensions-5.2.5nb4, Maintainer: pkgsrc-users

This package provides tools for working with various Kan extensions and Kan
lifts in Haskell.

Among the interesting bits included are:
* Right and left Kan extensions (Ran and Lan)
* Right and left Kan lifts (Rift and Lift)
* Multiple forms of the Yoneda lemma (Yoneda)
* The Codensity monad, which can be used to improve the asymptotic
complexity of code over free monads (Codensity, Density)
* A "comonad to monad-transformer transformer" that is a special case of a
right Kan lift. (CoT, Co)

math/hs-kan-extensions: Fix build with GHC 9.8

This breaks build with the currently default GHC 9.6. Please bear with me
until I switch the default compiler.
