/**
 * @assertion Evaluation of the cast expression e as T proceeds as follows:
 * The expression e is evaluated to a value v.
 * Then, if T is malformed or deferred type, a dynamic error occurs.
 * Otherwise, if the interface of the class of v is a subtype of T, the cast
 * expression evaluates to v.
 * Otherwise, if v is null, the cast expression evaluates to v.
 * In all other cases, a CastError is thrown.
 * @description Checks that if T is deferred type, then a compile error occurs.
