type t 
The universal type
type 'a key 
Conversion between the universal type and 'a
val new_key : ?eq:('a -> 'a -> bool) ->
?hash:('a -> int) ->
?print:('a -> string) -> unit -> 'a key
Create a new key. Values packed with a given key can only be unpacked by the same key.
print : a printing function to print the content of a universal value. Default just returns "opaque".
val pack : key:'a key -> 'a -> t
