Synopsis

Extracting types from HsSyn

Other HsSyn functions

mkHsApp :: forall (id :: Pass). LHsExpr (GhcPass id) -> LHsExpr (GhcPass id) -> LHsExpr (GhcPass id) #

mkHsAppTy :: forall (p :: Pass). LHsType (GhcPass p) -> LHsType (GhcPass p) -> LHsType (GhcPass p) #

mkHsCaseAlt :: forall (p :: Pass) body. LPat (GhcPass p) -> Located (body (GhcPass p)) -> LMatch (GhcPass p) (Located (body (GhcPass p))) #

A simple case alternative with a single pattern, no binds, no guards; pre-typechecking

conLikeResTy :: ConLike -> [Type] -> Type #

Returns the type of the whole pattern

re-exported from TcMonad

type TcId = Id #
