Parse error when using ' with promoted kinds
The following code generates a parse error:
{-# LANGUAGE DataKinds #-}
data Proxy a = Proxy
foo :: Proxy '['[True, False],'[False]]
foo = ProxyThe problem is that the '[' prefix to the type index is parsed as a character. Rewriting that string as '[ ' fixes the problem.
This is admittedly a very low priority problem, but it seemed to be enough of an infelicity to be worth reporting.
This was tested on 7.5.20120420.
