Asyncio tasks getting cancelled

Hi all,
I'm having trouble with asyncio. Apparently tasks (asyncio.create_task)
are not kept referenced by asyncio itself, causing the task to be
cancelled when the creating function finishes (and noone is awaiting the
corresponding futue). Am I doing something wrong or is this expected
behavior?
The code sample I tried:
> import asyncio
>
> async def foobar():
> print(1)
> await asyncio.sleep(1)
> print(2)
>
> async def main():
> asyncio.create_task(foobar())
> #await asyncio.sleep(2)
>
> loop = asyncio.get_event_loop()
> asyncio.run(main())
> loop.run_forever()
The sample does print "2" only when uncommenting the asyncio.sleep(2)
line.
Greetings.
