Nan::Callback SetWeak #891
Description
Hey.
I need to store V8 callbacks as weak references, with the finalizer callback so I can remove the reference when appropriate.
I've worked out how to do this with v8::Function, but I was hoping to keep the Nan::Callback wrapper intact in case of future API changes. Unfortunately the documentation is quite bare.
Is there a way to do this?

Nan::Persistent<v8::Function>::SetWeak()coupled withNan::Call()to actually invoke the function should do it.Nan::Callbackcould in theory be extended to offer that functionality (internally it already uses aNan::Persistent<v8::Function>) but I don't know, that's probably too esoteric and uncommon. ANan::Callbackis usually embedded in some other weak object.
