NFE's are safe to use where IE8 support isn't needed*. (function aa(){}).name; // "aa" As for using Object IDs and Object Pooling, lexically-scoped values have benefits over global ID generators (as your counter). The values can be passed in as a parameter to the Factory (useful with Private Proxy). There other benefits to this pattern regarding memory management and application design.
