I did not assume totally opaque -- but code objects are not very introspection friendly (and they have no strong compatibility guarantees).

If I understand the proposal correctly, there wouldn't be any point in trying to introspect the lambdas/thunks/whatever. They're only there to provide a level of lazy evaluation. You would evaluate them and then introspect the returned data structure.
