/// @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 local variable or formal parameter then e evaluates to the
///   current binding of id.
/// @description Checks that reference to a loop counter captured by a closure
/// results in unique binding.
