> Currently, invoking python from C++ requires a lot of boilerplate. For
> example, see any class named {{/\w+Vtable/}} which holds a bundle of function
> pointers and a single OwnedRef to a python object accessed by those
> functions. This is unnecessarily baroque for adding simple callbacks and we
> could instead have a general purpose utility similar to std::bind which can
> bring a python object into closure.
