See, I love it when this happens:

Federico: "hi, please help me make fire by rubbing sticks"

Sebastian: "here, have this high-tech oven instead"

Having this example of all the GObjects bells and whistles used from
Rust would be *VERY* helpful for the code generator!

I will definitely start looking at gstreamer-rs and the gtk-rs
infrastructure.  From librsvg I've only interacted with cairo-rs, which
doesn't use GIR, and a bit of the glib::translate stuff - none of the
fancy GObject wrappers.

I love the idea of having gobject_gen!() also generate Rust entry
points that look just like what gtk-rs would have.

Thanks for all the suggestions; it is very encouraging to know where to
steal examples of use :)

Ideally we would also be able to emit GIR information directly - since
the procedural macro can basically do anything in addition to emitting
tokens, maybe we can have it spit a cratename.gir/typelib on the
side...
