/**
 * @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 the declaration of a library variable or top-level getter, 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:].
