Indeed.  I heard a rumor[*] that there's at least one package in the
cheeseshop that consists of a one-liner.

On the other hand, we have multiprocessing examples in the docs that are
longer than that, so it sounds like a great asyncio example to me,
especially given that Victor says we don't have enough examples yet.


[*] https://pypi.python.org/pypi/first  It's not *actually* a one
liner, but you could write it as one, and the actual code isn't
much heavier :)
