datadata TyThing

A global typecheckable-thing, essentially anything that has a name. Not to be confused with a TcTyThing, which is also a typecheckable thing but in the *local* context. See GHC.Tc.Utils.Env for how to retrieve a TyThing given a Name.

datadata TcTyThing

#

A typecheckable thing available in a local context. Could be AGlobal TyThing, but also lexically scoped variables, etc. See GHC.Tc.Utils.Env for how to retrieve a TyThing given a Name.
