Use native clone methods when available #2719
Conversation
Just a little of feature detection to leverage the power of native clone!

Array.clone clones also eventual objects inside the array. Doing a early return here using return this.slice(0); would keep the objects reference and add a new behaviour. http://jsfiddle.net/syv2he8o/

The Object.create function creates a new object that inherits directly from the one passed as the first argument, in opposite the Object.clone creates a new object with always the base Object prototype, this is actually changing the Object.clone behavior. https://jsfiddle.net/AmraniCh/u86c0qoL/

@AmraniCh: In your fiddle, you should use Array.clone with arrays and not Object.clone

@SergioCrisostomo Actually it Object.clone, I'm just making a test with the array type.
The Mootools Object.clone always clone an object and return a new one with the Object prototype, if we add the return Object.create(object) then the Object.clone will use the object passed as an argument (can be an array, function ..) as a prototype of the newly created object, which is not the native behavior of the Object.clone.
