Description
When debugging the container and showing a service with it's arguments (debug:container SomeService --show-arguments), it shows resolved services in arguments. But usually what I need to debug is not what service it injects, but why. And the answer is usually "there is an alias" that autowiring used to resolve this.

The command could show the whole resolve chain. Instead of Service(core.ticketsEvents) it could show Alias(Service_Tickets, Service(core.ticketsEvents)) for following service definition:

 Service_Tickets:
  alias: core.ticketsEvents

And following service:

class SomeService {
   __construct(Service_Tickets $tickets) {
   }
}
