Description
Description
If a user wants to operate with the non-default output of RVs, they have to do rv.make_node() or rv().owner.outputs none of which is ideal or very readable.
I suggest adding a kwarg like return_rng=True that returns both (better names welcome)

Research direction
Start at the RandomVariable call entry point and inspect how its default output and non-default outputs are exposed. Define the optional return_rng behavior and output names, then verify that callers can receive both the regular result and the next RNG without using make_node() or owner.outputs.
