Some eta expansions required to build with GHC-9.0 #356

Closed recursion-ninja closed 3 years ago

recursion-ninja commented 3 years ago

Part of GHC 9.0 is the simplified subsumption in the type system, which effects code which relied on deep skolemization. The diagrams-lib package does rely on deep skolemization and does not build with GHC 9.0 without some eta expansions to help the type checker. See the migration guide for more information.

This pull request applied the eta reductions required to build with GHC 9.0.
