| Forbidden extension, f.arguments |
| info: | |
| ECMAScript function objects defined using syntactic constructors in strict mode code must |
| not be created with own properties named "caller" or "arguments". Such own properties also |
| must not be created for function objects defined using an ArrowFunction, MethodDefinition, |
| GeneratorDeclaration, GeneratorExpression, AsyncGeneratorDeclaration, AsyncGeneratorExpression, |
| ClassDeclaration, ClassExpression, AsyncFunctionDeclaration, AsyncFunctionExpression, or |
| AsyncArrowFunction regardless of whether the definition is contained in strict mode code. |
| Built-in functions, strict functions created using the Function constructor, generator functions |
| created using the Generator constructor, async functions created using the AsyncFunction |
| constructor, and functions created using the bind method also must not be created with such own |
| properties. |
