Runtime Type Checking
The Cast class provides a rudimentary run-time type checking. By default it simply checks that the passed in object is of a given type but it can be overridden by types which have to do more complex checking to ensure the types are correct.
Definition
struct Cast {
var (*cast)(var, var);
};
