 * @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 static method, top-level function or local function then e
 *   evaluates to the function defined by d.
 * @description Checks that reference to a static method is evaluated correctly.
