         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|, |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.

-        If an implementation extends non-strict or built-in function objects with an own property named `"caller"` the value of that property, as observed using [[Get]] or [[GetOwnProperty]], must not be a strict function object. If it is an accessor property, the function that is the value of the property's [[Get]] attribute must never return a strict function when called.
