 Just an idea I wanted to get out there, I don't think it causes parsing
 ambiguity

 {{{#!hs
 -- id :: forall a. a -> a
 id :: a. a -> a

 -- everywhere :: (forall b. Term b => b -> b) -> (forall a. Term a => a ->
 a)
 everywhere :: (b. Term b => b -> b) -> (a. Term a => a -> a)
 }}}

 I think it looks beautiful but clearly more difficult to Google or grep
 for.
