    13.3.3.6 Runtime Semantics: IteratorBindingInitialization

    BindingElement : BindingPatternInitializer opt

    1. If iteratorRecord.[[done]] is false, then
       a. Let next be IteratorStep(iteratorRecord.[[iterator]]).
       [...]
       e. Else,
          i. Let v be IteratorValue(next).
          [...]
    4. Return the result of performing BindingInitialization of BindingPattern
       with v and environment as the arguments.
