How can I call python functions that rely on "event_loop" inside go blocks?

Comienza con el ejemplo mínimo de core.async go del issue y el traceback que muestra que asyncio.get_event_loop se ejecuta en un Dummy thread. Lee la ruta de llamadas de Python de libpython-clj2 y el contexto de ejecución de core.async go para determinar si se puede admitir el acceso al bucle de eventos. Se considerará terminado cuando exista una forma documentada y funcional de llamar a estas funciones de Python desde bloques go, o una explicación clara de que este enfoque no es compatible.

Huge thanks for the great library. I'm wondering if the following is possible.

The problem

I want to call python functions with asyncio.get_event_loop() inside go blocks.

The get_event_loop is buried deep in the python code base, so I can't simply swap every required event loop to some new event loop that I create.

I haven't come up with a way to write a wrapper, and setting the event loop manually does not help.

I'm not seeking to solve the exception, because I think my approach seems wrong and the exception is expected, but rather, I'm asking for a way for my goal.

Many Thanks!

A minimal example that crashes

(ns main.playasync
  (:require [libpython-clj2.require :refer [require-python]]
            [libpython-clj2.python :refer [py. py.. py.-] :as py]
            [clojure.core.async :as async :refer [>! <! chan go]]))

(require-python '[agen]
                '[builtins :as python]
                '[asyncio])

(comment
  (go
    (let [ev-loop (asyncio/new_event_loop)]
      (asyncio/set_event_loop ev-loop)
      (asyncio/get_event_loop))))

will raise an exception
