Expected Behavior

Auto named factory functionality allows skipping the next code boilerplate code:

container.bind<interfaces.Factory<ServiceHandler>>("Factory<Elements>")
  .toFactory<ServiceHandler>((context: interfaces.Context) => (name: string) => {
    return context.container.getNamed<ServiceHandler>("Factory<Elements>", name)
  })

Current Behavior

Current behaviour forces to duplicate the same factories for different types.
Code above will be the same for a factory that produces elements and for a factory that produces components.

Possible Solution

A possible solution is creating toAutoNamedFactory method in container. I've created PR where I implemented this solution. You can review it here
