Is there a way in C to check whether a class/object has specific method defined? #604

The method could be defined either in Wren or foreign. As a developer, I'd like to be able to check whether it was already there before invoking it.

Right now, you can only test it by inheritance. But implementing such feature so trivial that you can do it in many ways. First time I did it was by interrogating the class. And one off the last time was by implementing a mirror API/module, that extracted all the methods signatures.
