 - No implementations are provided
 - Docs can be optionally specified for the protocol and the functions, via
   elegant JS hack.
 - The above yields a set of polymorphic functions and a protocol object
-- The resulting functions dispatch on the type of their `'this'` argument, and
-  thus must have it in the list of arguments.

 `protocol` will generate an interface containing a corresponding functions.
 returned interface may be used to extend data types with it's implementations:
