/**
 * @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.
 * ...
 * • If d is a local variable or formal parameter then e evaluates to the
 *   current binding of id.
 * @description Checks that a reference to a variable in a loop is evaluated
 * correctly in closures nested inside that loop.
