ah... because introspection functions aren't JS Function objects...

no, the atk_label argument is just being ignored: you'll get the same
error if you call "Atk.Object.prototype.get_name()" with no argument.
The problem is that it's passing "Atk.Object.prototype" as the argument
to atk_object_get_name(), and that's a JavaScript internal object, not
an AtkObject instance.

gjs automatically translates between JS proxies and underlying GObjects
as needed.

Oh, no, I meant StallyLabel. If stally_label_get_class() was overriding
atk_object_class->get_name, then there'd be no way to access that method
from gjs. Not that this matters at this point since there isn't even any
way to get the original AtkObject get_name method either.

Probably the easiest solution for now is to just add a C method
"shell_get_accessible_name (AtkObject *obj)" or something, that calls
atk_object_get_name(obj), and then you can use
"Shell.get_accessible_name(atk_label)" from JS.
