You know, I was looking at the PyGobject code, which basically does the same
thing. It looks at the methods and properties and such and creates the object
at that time. I'll look at that, that would probably be best.
I'm hoping to get some demonstration code soon... The documentation for
gobject introspection doesn't seem very good, more about making your own glib
types and classes be able to be introspected, rather than how to use
introspection in your own code for calling methods from existing classes. I
did see something on how ruby created bindings for gtk, and how you can use it
in your language, so I'll try to find that again, in addition to looking at the
python source.... It will be a while before this gets to the point of
pygobect, that code does a lot of stuff, including creating new gobject types
dynamically based on python code.

When I wrote an Objective-C bridge, I used introspection at class creation
time: I overloaded ObjectiveC->`[]() so that when, for example,
ObjectiveC.NSObject was accessed, a c-method performed introspection of the
NSObject class and created a program dynamically using the C level module API:
start_new_program() and friends. Methods were trampolines generated using
libffi This provided relatively good runtime speed of method calls (as they
were  c methods that used libffi combined with the objective-c API) without the
overhead of performing `[] and introspection on each method call. I also built
a system of overlays that could provide custom mixing methods for situations
where the generic binding wouldn’t suffice. Perhaps something like this could
be used to provide optimal performance?

Yeah, that's what the gtk2 module does, I'm wondering if I can add functions to
a class (in the c code) that has already been created and ended using
end_program().

Overloading the `-> operator should work.
