Readme for kan-extensions-5.2.2
[back to package description]kan-extensions
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 (
RanandLan) - Right and left Kan lifts (
RiftandLift) - Multiple forms of the Yoneda lemma (
Yoneda) - The
Codensitymonad, 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. (
