Test1>:i PrelGHC.RealWorld
-- PrelGHC.RealWorld is a primitive type constructor
foreign import type dotnet PrelGHC.RealWorld

   Why dotnet?


Test1>:!cat Test1.hs
module Test1 where
data A = Int :| Int
Test1>:i A
-- A is a type constructor, defined at Test1.hs:2
data A = :| Int Int

    Invalid syntax.


Test1>:i ()
-- () is a data constructor
():: ()

-- () is a type constructor
data*** Exception: types/TyCon.lhs:478: Non-exhaustive patterns in function tyConTheta
