Outputable HsWrapper # 

mkWpFuns :: [(TcType, HsWrapper)] -> TcType -> HsWrapper -> HsWrapper Source #

mkWpFuns [(ty1, wrap1), (ty2, wrap2)] ty_res wrap_res, where wrap1 :: ty1 "->" ty1' and wrap2 :: ty2 "->" ty2', wrap3 :: ty3 "->" ty3' and ty_res is either ty3 or ty3', gives a wrapper (ty1' -> ty2' -> ty3) "->" (ty1 -> ty2 -> ty3'). Notice that the result wrapper goes the other way round to all the others. This is a result of sub-typing contravariance.

unwrapIP :: Type -> CoercionR Source #

Create a Coercion that unwraps an implicit-parameter or overloaded-label dictionary to expose the underlying value. We expect the Type to have the form `IP sym ty` or `IsLabel sym ty`, and return a Coercion `co :: IP sym ty ~ ty` or `co :: IsLabel sym ty ~ Proxy# sym -> ty`. See also Note [Type-checking overloaded labels] in TcExpr.

Create a Coercion that wraps a value in an implicit-parameter dictionary. See unwrapIP.
