cloudpickle is used as self.pickler = Pickler(self.buffer) in handle_unsupported_write:

def handle_unsupported_write(self, buffer, obj):
        if self._unsupported_callback is None or self._unsupported_callback(obj):
            buffer.write_bool(True)
            self.pickler.dump(obj)
        else:
            buffer.write_bool(False)

What would you like to do with it?

@esafak We need to support the serialization of any types in fory that can be serialized by pickle/cloudpickle
