Contexts "branch", so if you store something in the context before asyncio.run
it will store it in the current thread state. And then asyncio.run will
New submission from Jason Chen :
import asyncio
from contextvars import *
var = ContextVar('VarTest', default=None)
def get_var(tag=None):
obj = var.get()
if obj is None:
obj = object()
var.set(obj)
print(f'{tag=}: get_var result is {obj=}')
return obj
async
