    ClassDeclaration : class BindingIdentifier ClassTail

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

    14.5.14 Runtime Semantics: ClassDefinitionEvaluation

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

    MethodDefinition : PropertyName ( StrictFormalParameters ) { FunctionBody }

    [...]
    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.

    23. Let iteratorRecord be Record {[[iterator]]:
        CreateListIterator(argumentsList), [[done]]: false}.
    24. If hasDuplicates is true, then
        [...]
    25. Else,
        b. Let formalStatus be IteratorBindingInitialization for formals with
           iteratorRecord and env as arguments.

    BindingElement : BindingPatternInitializer opt

    [...]
    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.
