I'm trying to access the introspection data from Javascript inside GJS.
Right now I can list infos from the introspection data using the following script :

const GI = imports.gi.GIRepository;

let repo = GI.Repository.get_default();
let nInfos = repo.get_n_infos('GtkClutter');
for (let i = 0; i < nInfos; i++) {
    let info = repo.get_info('GtkClutter', i);
    log(info.get_name());
}

My problem is that all info are GIBaseInfo and the GIBaseInfo doesn't have very much data.
All the structures like :
 - GICallableInfo
 - GIConstantInfo
 - GIObjectInfo
 - etc...

aren't actual GTypes and therefore are invisible in the introspection data.

So I just can't do very much with the introspection data at the moment.
Is there a plan to rework the way the structures describing the introspection data?
