RFC: Run Python from Ruby and Ruby from Python

  Calling Python functions from the Ruby language

Yeah, I know there are few libraries that do similar things: pycall.rb and rb_call, and there is also rubypython, but it's not supported and doesn't work with Python 3. I used pycall to create matplotlib charts from Ruby, it's great, and I'm gonna use part of its code, type conversion implementation, for example. But I don't think it's enough, it's like a one way bridge, I want more, I want to call Python from Ruby and Ruby from Python at the same time: create an Airfow PythonOperator, invoke Ruby code inside, store some value into XCom. What about rb_call, I don't like how it's implemented at all, it starts a separate process and serializes data using MessagePack RPC, so you can't use callbacks. It's not even possible to pass a Python object as an argument or call Ruby method that requires a block. And of course it's not effective.
