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.

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).
