Bug report
Bug description:
With the code from PR 122564, no branches are indicated for an async for. In the example below, both branches for the if also unexpectedly present (through co_locations) as "going out of scope":
import asyncio
async def g():
yield 1
yield 2
x = 0
async def fun():
global x
async for v in g(): # line 11
if v > 0:
x += v
x += 3
print(x)
asyncio.run(fun())Results:
