| /// @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. |

| /// G<T1,...,Tn> and G is generic type with different number of parameters, then |
| /// T is not malformed (see Types/Parameterized Types) and CastError is thrown, |
