    gc.get_objects() return all the objects tracked by the garbage collector. This is useful, but right now there is no way of knowing in which generation each object is currently on. This information can be beneficial to understand better the state of the garbage collector in a particular moment in time.

    This will allow knowing what are the oldest object tracked by the collector, gathering more fine-grained statistics about how generations are filled, better debugging and better insights about the internal structure of the generations.

    To allow this, I propose a new optional parameter to gc.get_objects, allowing the user to specify the generation to get the objects from.
