Yes, you'd usually either store a Persistent in the C++ class itself or
maintain a map.
The Persistent would usually be weak, so you get notified if the object is
no longer needed by V8, and you can create new Local handles to the js
object when needed.
A common pattern to get from the js object
What exactly do you want to store; just one class instance - or do you have an
existing C++ class that you are extending to be v8 compatible? There is a giant
difference between these cases.
The first case is what I am doing for nodejs currently; I am taking an existing
c++ class (Fl_Window) an

Right, Handle<> (and Local<>) can only be stack allocated and have to live
within a HandleScope. If you want to store a reference to a V8 object, you
need a Persistent<>, see esp. https://developers.google.com/v8/embed#handles

To really store something:

Replace Value with something like Array, for example. That will give you an
ever-existing value, not devoured by the GC. That, at least, works in my case
