typelits-witnesses v0.4.0.0 Release Notes

  • 🚀 https://github.com/mstksg/typelits-witnesses/releases/tag/v0.4.0.0

    June 20, 2019

    • Complete overhaul of GHC.TypeLits.Witnesses to more or less match the interface of singletons. This changes the role of the module to be a "lightweight" version of the singletons library as it pertains to Nat and Symbol.
    • Removal of the GHC.TypeLits.List module. We could perform the same overhaul as GHC.TypeLits.Witnesses, but it is complex enough that it would be better to just use singletons instead at that point.
    • Remove all external dependencies, except for base and dependent-sum.
    • Break compatibility with GHC < 8.2
