// example: http://jsfiddle.net/QVqHs/
function clone(o) {
return Object.create(
Object.getPrototypeOf(o),
getOwnPropertyDescriptors(o)
)
}
function getOwnPropertyDescriptors(o) {
return Object.keys(o).reduce(getPropertyDescriptor.bind(o), {})
}
function getPropertyDescriptor(acc, key) {
acc[key] = Object.getOwnPropertyDescriptor(this, key)
return acc
}
