Let me re-iterate.  I really think, there should be a
variant for consecutive chunks of -- comments, too.  The
latter are better handled by Emacs' font-locking and I don't
really want to compromise on the visual presentation in the
editor.  For example,

  -- --
  -- This is a great function
  -- that I use a lot
  foo :: ..

could be equivalent to

  {----
     This is a great function
     that I use a lot
  -}
  foo :: ..

Cheers,
