var create_assign = require("create-assign");

//create_assign(proto, properties /, properties2, .../)

var a = {

};
var b = {
f3: function () { return 3; },
f4: function () { return 4; },
};
var c = create_assign(a, b, {
f2: function () { return 22; },
f3: function () { return 33; },
});

assert(
