Parsing failure with type-level lists

[KaneTW]

The following valid Haskell code

{-# LANGUAGE DataKinds, TypeOperators, PolyKinds #-}
module Bug where

data A (a :: [*]) 
data B 
data a :> b
data a :<|> b

type Fail = A '[] :> ( A '[] :<|> B)

fails to parse with haskell-mode. When using haskell-indentation-mode, pressing TAB fails with No catch for tag: parse-error, "Illegal token: )"

Can you add a test case in `tests/haskell-indentation-tests.el`?

Just tested with HEAD. Seems to be fixed.
