/**
 * @assertion Evaluation of an identifier expression e of the form id proceeds
 * as follows:
 * Let d be the innermost declaration in the enclosing lexical scope whose name
 * is id or id=. If no such declaration exists in the lexical scope, let d be
 * the declaration of the inherited member named id if it exists.
 * ...
 * • Otherwise, e is equivalent to the property extraction this.id.
 * @description  Checks that identifier expression can refer to an inherited
 * member.
