/**
 * @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. 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 local variable is evaluated correctly in closures.
