    // discuss at: http://phpjs.org/functions/aggregate_properties_by_list    // +   original by: Brett Zamir (http://brett-zamir.me)
    // %          note 1: We can't copy instance properties, as those require instantiation (with potential side-effects when called)
    // %          note 1: We've chosen not to assign to or create a prototype object on the destination object even if the original object had the properties on its prototype
    // *     example 1: var A = function () {};
    // *     example 1: A.prototype.prop = 10;    // *     example 1: var b = {};
    // *     example 1: aggregate_properties_by_list(b, 'A', ['prop'], false);
    // *     returns 1: undefined
