TysWiredIn
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

List
Tuples
mkBoxedTupleTy :: [Type] -> TypeSource
Build the type of a small tuple that holds the specified type of thing
tupleTyCon :: Boxity -> Arity -> TyConSource
Unit
Parallel arrays
mkPArrTy :: Type -> TypeSource
Construct a type representing the application of the parallel array constructor
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 -> DataConSource
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 -> BoolSource
Check whether a type constructor is the constructor for parallel arrays
isPArrFakeCon :: DataCon -> BoolSource
Checks whether a data constructor is a fake constructor for parallel arrays
