Synopsis

ForAllTyFlags

data ForAllTyFlag Source #

ForAllTyFlag

Is something required to appear in source Haskell (Required), permitted by request (Specified) (visible type application), or prohibited entirely from appearing in source Haskell (Inferred)? See Note [VarBndrs, ForAllTyBinders, TyConBinders, and visibility] in GHC.Core.TyCo.Rep

isVisibleForAllTyFlag :: ForAllTyFlag -> Bool Source #

Does this ForAllTyFlag classify an argument that is written in Haskell?

isInvisibleForAllTyFlag :: ForAllTyFlag -> Bool Source #

Does this ForAllTyFlag classify an argument that is not written in Haskell?

coreTyLamForAllTyFlag :: ForAllTyFlag Source #

The ForAllTyFlag on a (Lam a e) term, where a is a type variable. If you want other ForAllTyFlag, use a cast. See Note [Required foralls in Core] in GHC.Core.TyCo.Rep
