-- A 'Dict' reifies a constraint in the form of a first class value. The 'Dict'
-- type is not serializable: how do you serialize the constraint that values of
-- this type carry? However, for any constraint @c@, a value of type @'Closure'
-- ('Dict' c)@ /can/ be serialized and sent over the wire, just like any
-- 'Closure'. A /serializable dictionary/ for some constraint @c@ is a value of
-- type @'Closure' ('Dict' c)@.
