Comment (by Iceland_jack):

 I like that, GHCi could display associated types:

 {{{#!hs
 >>> :type sum
 sum :: SBool single -> IsSingleton single -> Natural
 >>>
 >>> :types sum
 sum :: SBool single -> IsSingleton single -> Natural

 sum STrue  :: Natural -> Natural
 sum SFalse :: [Natural] -> Natural
 }}}
