The information about how GHC's parser currently handles infixes.  The 
intent of the -ddump-xxx flags (I think) is to give a readable 
representation of ghc's internal state, e.g. for debugging.

However it very well might be that omitting those parentheses would 
yield a Haskell module equivalent to the original file, which would be a 
nice thing to be able to get somehow, anyway.
