ToPropertyDescriptor with an undefined getter or setter

# Oliver Hunt (15 years ago)

What is the expected behaviour of ToPropertyDescriptor if I provide undefined values for the get or set properties? eg. var o={}; Object.defineProperty(o, "foo", {get: undefined}); Object.getOwnPropertyDescriptor(o, "foo"); // ???

What is the expected behaviour of ToPropertyDescriptor if I provide undefined values for the get or set properties?  eg.
var o={};
Object.defineProperty(o, "foo", {get: undefined});
Object.getOwnPropertyDescriptor(o, "foo"); // ???

An accesor descriptor with [[Get]] and [[Set]] undefined.
