/**
 * @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 the declaration of a library variable, top-level getter or
 *   top-level setter, then e is equivalent to the getter invocation id.
 * @description  Checks that if evaluation of the initializer expression of a
 * library variable is not successful, the variable is initialized with [:null:].
