* Add performance benchmark similar to ActiveRecord
* Lazily find_or_create_resource_for_collection to not incur the overhead for empty arrays and arrays of primatives
* #duplicable? is faster than inline rescues when the object is not duplicable
* Don't constantly raise and handle NameError, raising is expensive
* Even when a resource is nested inside a module, always look inside the class first for the resource definition so we don't overwrite classes all the time
