For the Python guestfs bindings we originally planned to write an
idiomatic (ie. OO in that case) API on top of the raw generated
bindings, but never really got around to it.  I'm not convinced it's
really a good idea because you end up chasing new APIs.  Remember the
whole point of the generator is that new APIs are instantly available
in all languages as soon as they are added upstream.
