intrinsic-superclasses

A template haskell implementation of the Intrinsic Superclasses Proposal, which allows defining all typeclass methods at the "root" of the class heirarchy, rather than an instance declaration per class.

There are currently a number of limitations compared with the full language proposal (see: issues).

Functionality is added as-needed so drop an issue (and/or a pull request, if you're feeling ambitious 😉) if you have a use-case that isn't covered now.
