You can also add a property to all objects with an array of keys in the order you want (if you can guarantee it won't conflict with existing properties, or can escape those), or turn them into a {k, o} array where k is the key array and o the object or if you don't care about looking up keys then either a {k, v} array where v is a value array or an object where keys are prefixed with their position or putting the position in the value as an array of value and position.
