code hints in inherited class by Class.create not showing, later use guess hint causes existing hint changed

1. following following code snippet, try to get code hint after bruce.

var Vulnerable = {
    wound: function (hp) {
        this.health -= hp;
    },
    kill: function () {
    }
};

var Person = Class.create(Vulnerable, {
    initialize: function () {
        this.health = 100;
    }
});

var bruce = new Person();
bruce.

->code hints are: kill, wound, missing "initialize".
2. type initialize() after "bruce.".
3. get code hint by type bruce. again
->code hints now: initialize, wound, "kill" is removed

Expect:
at step 1, "initialize" should be found.
at step 3, code hint should be: initialize, kill, wound

I opened similar issue against tern. Marinj replied with following:
"It appears that Prototype's Class.create is too complex a function to be properly interpreted by Tern. The best solution is probably for someone to write a JSON definition file (similar to defs/jquery.json) for the library. If you want to put in the effort, or if you can point me to a machine-readable specification of the Prototype interface, that'd be much appreciated."

So maybe we can do something for this? thanks.

@adrocknaphobia Hi Adam, would you mind putting this on the community backlog. This way people could vote on it, we actually don't know how many would run into something like this.
