/// @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 the initializer expression is evaluated at
/// the first use of a library variable.
