    ClassExpression : class BindingIdentifieropt ClassTail

    1. If BindingIdentifieropt is not present, let className be undefined.
    2. Else, let className be StringValue of BindingIdentifier.
    3. 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

    AsyncMethod : async PropertyName ( UniqueFormalParameters ) { AsyncFunctionBody }

    1. Let propKey be the result of evaluating PropertyName.
    2. ReturnIfAbrupt(propKey).
    3. If the function code for this AsyncMethod is strict mode code, let strict be true. Otherwise
       let strict be false.
    4. Let scope be the LexicalEnvironment of the running execution context.
    5. Let closure be ! AsyncFunctionCreate(Method, UniqueFormalParameters, AsyncFunctionBody,
       scope, strict).
    [...]


    14.1.19 Runtime Semantics: IteratorBindingInitialization

    FormalsList : FormalsList , FormalParameter

    1. Let status be the result of performing IteratorBindingInitialization for
       FormalsList using iteratorRecord and environment as the arguments.
    2. ReturnIfAbrupt(status).
    3. Return the result of performing IteratorBindingInitialization for
       FormalParameter using iteratorRecord and environment as the arguments.
