This could sometimes make the output verbose when the arguments themselves are tasks while including arguments in the signature in _format_coroutine.

$ cat /tmp/foo.py
import asyncio

async def foo(a, b): pass

async def main():
    task = asyncio.create_task(foo(1, b=1))
    task1 = asyncio.create_task(foo(1, b=task))
    print(repr(task))
    print(repr(task1))

asyncio.run(main())

$ python3.8 /tmp/foo.py
<Task pending name='Task-2' coro=<foo() running at /tmp/foo.py:3>>
<Task pending name='Task-3' coro=<foo() running at /tmp/foo.py:3>>

$ ./python.exe /tmp/foo.py
<Task pending name='Task-2' coro=<foo(a=1, b=1) running at /tmp/foo.py:3>>
<Task pending name='Task-3' coro=<foo(a=1, b=<Task pending name='Task-2' coro=<foo(a=1, b=1) running at /tmp/foo.py:3>>) running at /tmp/foo.py:3>>
