 * @assertion Evaluation of a throw expression of the form throw e; proceeds as follows:
 * The expression e is evaluated yielding a value v. If v evaluates to null, then a
 * NullThrownError is thrown. Otherwise, control is transferred to the nearest
 * dynamically enclosing exception handler, with the current exception set to v.
 * @description Checks that an expression statement of the form "throw e;" indeed raises an exception
 * and transfers control to the nearest enclosing exception handler if there is one.
