> As  suggested while working on Visitor API, I have came up with following proposal. The
idea is to support user defined DAG listeners.  The plan is to
> support limitated set of events for now and we could add more events
> in future.
> For the details functionality propvided check attached document.
> Please provide feedback on provided proposal.
