Description
We have @scalar_rule which basically follows the API of DiffRules.
I think we should have more.
I think @rrule which follows the API of ZygoteRules.adjoint
and a matchign @ffrule
Maybe a @DoesNotExist that declares that something is nondifferentiable.
Also something like ZygoteRules.@which (probably @which_frule and @which rrule,
to locate the rules that would be called.

Research direction
Start by reviewing the existing @scalar_rule API and its relationship to DiffRules. Compare the proposed @rrule, @ffrule, @DoesNotExist, @which_frule, and @which_rrule helpers with ZygoteRules.adjoint and ZygoteRules.@which; done requires a resolved scope and API design for the requested declaration and lookup helpers.
