happy to review a PR, at the moment I am too busy at work to do this myself :(

Working on one right now + updating redis to redis-py 3.0.

sidenote - we need better docs on testing... i spent hours getting unit tests to run.

UPDATE: Managed to bump redis-py to >=3, all unit tests are passing. (needed that for my project, as it uses redis-py>=3 as dependency already.

UPDATE 2: Also fixed a typo where async was not properly converted to async_. Trivial but important!
