	Provides a way to provide functionality that only applies in the real production environment, otherwise stubs out the function.
	
	Use this with **care** as this makes testability difficult and can lead to errors/bugs leaking into production.  This should really only be used for non-functional (fire-and-forget) components like error logging or analytics.
