Hey I'm wondering why there isn't a helper class for Persistent<T> which
will Dispose() a handle at the end of scope. It seems like right now v8
encourages lots of unfriendly cleanup code such as:
void function hello() {
Persistent<Thing> thing = Persistent<Thing>::New(...);
...
thing.Dispose();
}
This kind of code is difficult to maintain in many cases, and also
vulnerable to memory leaks when using C++ exceptions. I'd like to see a
version of Persistent<T> that behaves similarly to std::unique_ptr<T>. v8
already has helper classes like this with Isolate::Scope and Context::Scope.
Or perhaps there's a way to get what I want with local handles? I tried
something like this to no avail:
Persistent<Context> pcontext = Context::New(NULL, global);
Local<Context> lcontext = pcontext;
pcontext.Dispose();
Any advise would be appreciated!
