description: A trailing comma should not increase the arguments.length, using multiple args (static class expression async private generator method)
esid: sec-argument-lists-runtime-semantics-argumentlistevaluation
features: [async-iteration, class, class-static-methods-private]
flags: [generated, async]

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
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).
