      1. Let propKey be the result of evaluating PropertyName.
      2. ReturnIfAbrupt(propKey).
      3. If the function code for this GeneratorMethod is strict mode code,
         let strict be true. Otherwise let strict be false.
      4. Let scope be the running execution context's LexicalEnvironment.
      5. Let closure be GeneratorFunctionCreate(Method,
         StrictFormalParameters, GeneratorBody, scope, strict).

      23. Let iteratorRecord be Record {[[iterator]]:
          CreateListIterator(argumentsList), [[done]]: false}.
      24. If hasDuplicates is true, then
          [...]
      25. Else,

             iteratorRecord and env as arguments.

      ArrayBindingPattern : [ Elision ]
  
      1. Return the result of performing
         IteratorDestructuringAssignmentEvaluation of Elision with iteratorRecord
         as the argument.
  
      12.14.5.3 Runtime Semantics: IteratorDestructuringAssignmentEvaluation
  
      Elision : ,
  
      1. If iteratorRecord.[[done]] is false, then
         a. Let next be IteratorStep(iteratorRecord.[[iterator]]).
         b. If next is an abrupt completion, set iteratorRecord.[[done]] to true.
         c. ReturnIfAbrupt(next).
         d. If next is false, set iteratorRecord.[[done]] to true.
      2. Return NormalCompletion(empty).
