NegativeLiterals breaks an otherwise well-typed program
## Summary The following program fails to compile: ```haskell {-# LANGUAGE NegativeLiterals #-} module Test where tooLarge :: Int -> a tooLarge _ = errorWithoutStackTrace ("!!: index too large") {-# INLINABLE (!!) #-} xs !! n = foldr (\x r k -> r (k-1)) tooLarge xs n ``` with the error ``` /home/sandy/Test.hs:9:18: error: • Couldn't match type ‘Integer -> Int’ with ‘Int’ Expected type: Int -> t1 Actual type: (Integer -> Int) -> t1 • In the first argument of ‘foldr’, namely ‘(\ x r k -> r (k -1))’ ``` However, this program will compile successfully under `-XNoNegativeLiterals`. This might not be a minimal example, I didn't attempt to shrink it any further. ## Steps to reproduce Attempt to compile the above program. ## Expected behavior According to the documentation of `-XNegativeLiterals`, this shouldn't affect the types of the program. ## Environment * GHC version used: 8.8 and 8.6 Optional: * Operating System: * System Architecture:
