Thanks for the information.  I'll try to contact the author (Cc'ed
anyway).

The main differences of mine from that one are:

- 'dbus-define-proxy' is a macro instead of a function.  So, XML parsing
  and code generation happen at byte-compile time.

- it doesn't rely on introspection, but takes an interface definition in
  XML.  I think that's what other languages do these days.
