Description

This module is about types that can be defined in Haskell, but which must be wired into the compiler nonetheless. C.f module TysPrim

# Unit

# Parallel arrays

mkPArrTy :: Type -> Type

Construct a type representing the application of the parallel array constructor

parrTyCon :: TyCon

Represents the type constructor of parallel arrays

- This must match the definition in `PrelPArr`

NB: Although the constructor is given here, it will not be accessible in user code as it is not in the environment of any compiled module except `PrelPArr`.

parrFakeCon :: Arity -> DataCon

Fake array constructors

- These constructors are never really used to represent array values; however, they are very convenient during desugaring (and, in particular, in the pattern matching compiler) to treat array pattern just like yet another constructor pattern

isPArrTyCon :: TyCon -> Bool

Check whether a type constructor is the constructor for parallel arrays

isPArrFakeCon :: DataCon -> Bool

Checks whether a data constructor is a fake constructor for parallel arrays

parrTyCon_RDR :: RdrName

parrTyConName :: Name
