Because it's the same version that is from Prototype.js. I guess it was 
ported "as is" for compatibility with the library. But IMO, yes, native 
implementation could provide at least an option for this case (if 
needed). Though, that's said, you may implement in your way using 
`for-in` or getOwnPropertyNames + getPrototypeOf.
