[New-bugs-announce] [issue37299] RuntimeWarning is NOT raised

[YoSTEALTH]

New submission from YoSTEALTH <ritesh at stealthcentral.com>:

from asyncio import run


async def true():
    return True


async def false():
    return False


async def error():
    a = false()
    b = true()
    return await (a or b)
    # Good Error
    #   "RuntimeWarning: coroutine 'true' was never awaited print(await error())"


async def no_error():
    return await (false() or true())  # False
    # Bad Problem
    #   `RuntimeWarning` is not raised for 'true'.

    # Note
    #   The correct syntax is `return (await false()) or (await true()) as it should return `True`
    #   not `False`


async def test():
    print(await no_error())  # False
    print(await error())     # RuntimeWarning(...), False


if __name__ == '__main__':
    run(test())


- Tested in Python 3.8.0b1
- Why does `error()` return `RuntimeWarning` but `no_error()` does not?
