Eager-load multiple relationships through `@with`

Is your feature proposal related to a problem? Please describe.

It seems that it is currently not possible to eager-load multiple relationships through the @with directive.

Describe the solution you'd like

I think it should either be possible to use the @with directive more than once on a single field, or the @with directive should accept an array of relationships.

• Using the @with directive multiple times: I'm not sure if it's currently possible to use any directive more than once on a single field. Is this being prevented for some reason?
• Accepting an array of relations through the @with directive: The question is how to handle scopes then, should they be part of the relations array (e.g relations: ["relation" => ["scopeOne", "scopeTwo"]]?

Describe alternatives you've considered

I haven't found any alternative to overcome this issue.

Start by locating the implementation and tests for the @with directive and how a single relationship is currently specified. Compare the two proposed forms, including scoped relationships, and define which behavior and tests would establish support for multiple eager-loaded relationships.
