I see no problem with putting lazy loading in common.  Just because it's there doesn't mean swift has to use it. Common simply implies that they are modules used by several, but not necessarily all, projects.

There doesn't seem to be a way to proxy into an object itself.  I'd like to be able to specify a class (or a method) and have it lazy loaded into an object backend.  This is what import_object did automatically that makes it so versatile.  Admittedly it had an annoying bug that ate underlying exceptions, but imo, that is a bug that can be addressed.
