so, it is exactly the same as (assume the keys are in a closure i'm too lazy to type it all)

function Person(first, last){ var firstNameProperty = {}, // unique snowflake obj lastNameProperty = {} // yet another unique obj this[firstNameProperty] = first; this[lastNameProperty] = last; }

ES6 should be saving me from typing all the scoping hacks such as closure. not giving me syntax sugar for things i could do already without odd language constructs (now i have to run TWO loops to get my obj properties. which is what everyone is going to do anyway, since you can iterate on all the symbol properties anyway)
