The Getting Started example in the tutorial doesn't work for me

[DigitalChiller]

I decided to try out curio, so I copied a tutorial example https://curio.readthedocs.io/en/latest/tutorial.html#getting-started and ran it in the Python3 interpreter (same when you put it in a file, except you don't have to press ctrl-c for the last Traceback to appear):

>>> import curio
>>> async def countdown(n=10):
...     while n > 0:
...         print('T-minus', n)
...         await curio.sleep(1)
...         n -= 1
... 
>>> curio.run(countdown, 10)
Traceback (most recent call last):

I'm in a transitional period of preparing a new release and lot of things have changed. Documentation is currently tracking the master branch of Curio in Github. So, I would try that instead of any version downloaded from pypi.

Jup, the git version works fine. Thanks for the help :)
