// NOTE: we do not touch .__keys here as no renaming is ever done...

// XXX this essentially rewrites the whole map, is there a faster/better 
// 		way to do this???
// 		...one way would be to decouple order from the container, i.e.
// 		store the order in a separate attr/prop but this would require
// 		a whole new set of ordered "type" that would overload every single
// 		iteration method, not sure if this is a good idea untill we 
// 		reach a state whe JS "shuffles" (index-orders) its containers 
// 		(a-la Python)
