    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.

    Runtime Semantics: PropertyDefinitionEvaluation

    AsyncGeneratorMethod :
        async [no LineTerminator here] * PropertyName ( UniqueFormalParameters )
            { AsyncGeneratorBody }

    1. Let propKey be the result of evaluating PropertyName.
    2. ReturnIfAbrupt(propKey).
    3. If the function code for this AsyncGeneratorMethod 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 ! AsyncGeneratorFunctionCreate(Method, UniqueFormalParameters,
       AsyncGeneratorBody, scope, strict).

    13.3.3.6 Runtime Semantics: IteratorBindingInitialization
    ArrayBindingPattern : [ Elisionopt BindingRestElement ]
    1. If Elision is present, then
       a. Let status be the result of performing
          IteratorDestructuringAssignmentEvaluation of Elision with
          iteratorRecord as the argument.
       b. ReturnIfAbrupt(status).
    2. Return the result of performing IteratorBindingInitialization for
       BindingRestElement with iteratorRecord and environment as arguments.
