[webkit-dev] Ptr<T>

I just spent a while debugging an error in code I wrote. I added a couple new Foo* members to a class. And forgot to 0 them in one of the constructors. RefPtr<T>, OwnPtr<T> would have done this for me. But I wanted these to be weak pointers. How about we add a Ptr<T> (or WeakPtr<T> or AutoNull<T> or whatever) to wtf to stop this nonsense. -eric
