[capnproto] A client can implement a Function on the client side and the server will call back to it

[Jeffrey Qiu]

The calculator.capnp in examples mentioned:

# A client can create a Function that runs on the server side using
# `defFunction()` or `getOperator()`. * Alternatively, a client can*
* # implement a Function on the client side and the server will call
back*
* # to it.* However, a function defined on the client side will require
a
# network round trip whenever the server needs to call it, whereas
# functions defined on the server and then passed back to it are called
# locally.

How to do it with Python?

Hi Jeffrey,

Unfortunately the author of the Python implementation hasn't been active in
a while and I'm not sure if anyone else here knows the answer. You may have
to dig into the code a bit. I'm pretty sure this is supported, though.

Then how to do it with C++?

Ignore the question.
There is a sample function PowerFunction in the calculator client.
It is what I am looking for.
