This change set includes tests for most invocations of the SetFunctionName abstract operation in the ES2015 specification. Practical testing considerations preclude the introduction of tests for certain invocations: - The project is still vetting methods to sustainably test the semantics of the Destructuring Binding pattern across all valid productions. - 13.3.3.6 Runtime Semantics: IteratorBindingInitialization - 13.3.3.7 Runtime Semantics: KeyedBindingInitialization - Without a loader, there is no way to access a function object declared in an ExportDeclaration, so `name` assignment cannot be tested in these cases - 14.1.19 Runtime Semantics: InstantiateFunctionObject - 14.4.12 Runtime Semantics: InstantiateFunctionObject - 14.5.15 Runtime Semantics: BindingClassDeclarationEvaluation - 15.2.3.11 Runtime Semantics: Evaluation

IsAnonymousFunctionDefinition(Initializer) and IsIdentifierRef of
