We actually do this for Java, creating the JavaHL bindings. And
really, it isn't that much work (after the initial infrastructure is
built). They much better support Java idioms than any generated
wrapper could, and the maintenance burden is generally pretty low.

We could still use the swig-generated stuff to create most of the
boiler-plate between $TARGET_LANGUAGE and C, and then implement a
clean API on top of that. Or we could do something like the
object-model branch, or some other idea. (And then there are the
backward compat considerations...)
