/**
 * @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 and the current return value becomes
 * undefined.
 * @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.
