Go to Declaration Deep

I'm often tracing through layers and layers of assignment/passing with Go To Declaration.

It would be nice if there was an option like Go To Declaration Deep, which would follow a chain of declarations down to the source of a value, or as far as it could chain the jumps.

This would have to be some mix of Go To Declaration and Go To Implementation, since often these are arguments on an interface, but I think it would be fairly easy to get a basic implementation going.
