you're using gperl_object_type_from_package as the global typemap for GTypes,
but there are two registries for GTypes in the perl bindings ---- object
types, and boxed types.  that is, stuff registered via gperl_register_object
and gperl_register_boxed use two distinct private mappings between GTypes and
packages.  with a typemap you can't guarantee which type you're always
getting!

the universal wrapper, gperl_type_from_package, looks in both stashes, but
there are many instances in which it could be very wrong to do so; when
looking up the boxed wrapper for a given type, you don't want to find object
wrappers.

so, i would say that a typemap isn't an appropriate approach.  you'd be better
off minimizing the number of places where a GType is needed in your API, and
handling those manually.  this is how Glib and Gtk2 do it.

having said all that, in what context do you need the GType?
