Not everything supports comments

[hikari-no-yume]

I understand that there are limitations due to preserving comments in output, so we can't just discard them in a preprocessing stage. But there are some pretty egregious cases, these two in particular:

def foo # test
  if test # test
  end
end

This should be fixed in the grammar, right now all comments must be in their own line, which is most of the time what you want as adding them late in a line might make it not so visible.
