Sure, but let's give it a few weeks to mature.

:ok:

Yup, I'm just going to use it in some of my private projects for now and see what issues I (and others) hit until switching fully.

I think it's time. We should also convert to AVA for tests and some repos are using outdated AVA version which also needs upgrading. @shinnn Interested in doing this?

@shinnn Did you finish this? Can this be closed now?

XO has changed a lot since this though, so we should probably run the latest version on all the repos and fix issues.

Ping @shinnn :)
