Overview

Ensures that the memory/recollections that an actor uses are effectively global (using the actor name).

This is required to use Cucumber ParameterTypes because the block arguments are cloned before they are provided to the step definitions. This is intentional by the cucumber team to prevent leaking state between step definitions. See github.com/cucumber/cucumber-ruby/issues/1275.

The cloning of the actor means that is is effectively treated like a value object, and there will be many instances of the same actor instantiated in the execution of a single test.
