Reifying a GADT doesn't tell you the correct return type
Running this example:
{-# LANGUAGE GADTs, TemplateHaskell #-}
module Main (main) where
import Language.Haskell.TH
type S = T
data T a where
MkT :: S Int
$(return [])
main :: IO ()
main = putStrLn $(reify ''T >>= stringE . pprint)
gives the following result:
data Main.T (a_0 :: *) where Main.MkT :: Main.T GHC.Types.Int
Shouldn't the return type be Main.S GHC.Types.Int
instead?
