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.
