/**
* @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, 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 a parameterized type of the form
* G<T1,...,Tn> and G is malformed, then T is malformed, and TypeError is
* thrown, not CastError.
