 ### Accessing raw actors
 
 As you may have noticed, when you print an actor defined with Uranium, it won't show up as an actor - it'll show up as a "proxy" of an actor. This is because we can't actually get actors created on demand in NotITG - what happens instead is you get an object that _acts_ like an actor by calling all the same methods you pass into it, but isn't really one.
