| features: [class, class-static-methods-private, async-iteration] |
| flags: [generated, async] |
| info: | |
| 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). |

| |
| 13.3.3.7 Runtime Semantics: KeyedBindingInitialization |
| |
| [...] |
| 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). |
| c. ReturnIfAbrupt(v). |
| 4. Return the result of performing BindingInitialization for BindingPattern |
| passing v and environment as arguments. |
