 The Ocaml binding does not use user_data, because it is layered into two
 levels. The first one is just a one-to-one binding to the C interface.
 The second level (re-)builds a hierarchy of OO classes using the functions
 of the first level as pre-methods. Any additional data the binding needs
 can be added directly to the second level, without using the user_data
 field of the first one.

 Of course, this approach is probably not feasible for other languages.
