A workaround we've done is to write our own forEach method, but

If so, you could save the original and provide a new API to fetch the

Well, the other option is to try to write everything through the v8 API,

A Harmony Proxy looks like an object. When ANY member is accessed, you have a
function called that returns (or sets) the value. Sort of like a wildcard
getter and setter for the object in question. There was mention a while ago
