[Haskell-cafe] Lifting a value into a DataKind

Is it possible to automatically lift an arbitrary value into a type? i.e. I'm after a function of type `a -> Proxy (b :: a)`. More specifically, I'm wanting to be able to write a function that can convert an Enum (e.g. Bool or Ord) into such a Proxy, so I can actually write a function that looks like: `a -> (forall b. Proxy (b :: a) -> r) -> r` and use the `a` type as a selector value (to e.g. choose between type class instances). -- Ivan Lazar Miljenovic Ivan.Miljenovic@gmail.com http://IvanMiljenovic.wordpress.com
