deeplySkolemise :: TcSigmaType -> TcM (HsWrapper, [TyVar], [EvVar], TcRhoType) Source #
topInstantiate :: CtOrigin -> TcSigmaType -> TcM (HsWrapper, TcRhoType) Source #
Instantiate all outer type variables and any context. Never looks through arrows.
topInstantiateInferred :: CtOrigin -> TcSigmaType -> TcM (HsWrapper, TcSigmaType) Source #
Instantiate all outer Invisible binders
and any context. Never looks through arrows or specified type variables.
Used for visible type application.
deeplyInstantiate :: CtOrigin -> TcSigmaType -> TcM (HsWrapper, TcRhoType) Source #
instDFunType :: DFunId -> [DFunInstType] -> TcM ([TcType], TcThetaType) Source #
instStupidTheta :: CtOrigin -> TcThetaType -> TcM () Source #

newWanteds :: CtOrigin -> ThetaType -> TcM [CtEvidence] Source #
tcInstBinders :: [TyBinder] -> TcM (TCvSubst, [TcType]) Source #
This is used to instantiate binders when type-checking *types* only. See also Note [Bidirectional type checking]
tcInstBindersX :: TCvSubst -> Maybe (VarEnv Kind) -> [TyBinder] -> TcM (TCvSubst, [TcType]) Source #
This is used to instantiate binders when type-checking *types* only.
The VarEnv Kind gives some known instantiations.

Returns free variables of WantedConstraints as a non-deterministic set. See Note [Deterministic FV] in FV.
tyCoVarsOfCt :: Ct -> TcTyCoVarSet Source #
Returns free variables of constraints as a non-deterministic set
tyCoVarsOfCts :: Cts -> TcTyCoVarSet Source #
Returns free variables of a bag of constraints as a non-deterministic set. See Note [Deterministic FV] in FV.
