Cannot parse comma-separated guards

[konn]

hi2 cannot parse comma-separated guards.

For example, if I tap TAB at the next line to False | False, True -> print True, hi2 raises parse error:

main :: IO ()
main = case True of
  False | False, True -> print True

First of all, thank you for you bug reports and contributions!

Secondly, we are aware that hi2 doesn't support all of the modern Haskell syntax. (There are quite a few extensions it doesn't support.) We have some plans to do a major clean-up and add all of the missing syntax. But unfortunately, we are quite busy nowadays, so it's unlikely that we will get to it soon.

However, you are very welcome to send pull requests for these missing syntaxes! We will try to review and release them quickly. (I'll try to take a look at you pull request #10 today or tomorrow.)
