      ClassDeclaration : class BindingIdentifier ClassTail
  
      1. Let className be StringValue of BindingIdentifier.
      2. Let value be the result of ClassDefinitionEvaluation of ClassTail with
         argument className.

      21. For each ClassElement m in order from methods
          a. If IsStatic of m is false, then
             i. Let status be the result of performing
                PropertyDefinitionEvaluation for m with arguments proto and
                false.

      6. Let closure be FunctionCreate(kind, StrictFormalParameters, FunctionBody,
         scope, strict). If functionPrototype was passed as a parameter then pass its
         value as the functionPrototype optional argument of FunctionCreate.

      24. If hasDuplicates is true, then
          [...]
      25. Else,
          b. Let formalStatus be IteratorBindingInitialization for formals with
             iteratorRecord and env as arguments.

      2. If iteratorRecord.[[done]] is true, let v be undefined.
      3. If Initializer is present and v is undefined, then
         a. Let defaultValue be the result of evaluating Initializer.
         b. Let v be ? GetValue(defaultValue).
      4. Return the result of performing BindingInitialization of BindingPattern
         with v and environment as the arguments.
