 There are two types of casts in C#: the C-style `(T) o` throws if the object is not of the desired type, whereas `o as T` evaluates to `null` if it's not of the desired type. There's no '?' in this `null`-producing operator (this is probably only confusing if you use Kotlin).
 
-If an object being the wrong type is *exceptional*, throw an *exception* straight away. Having it reported as an NRE when there's no `null` in sight just delays debugging the problem.
