I’ve managed to get myself back to coding after an unexpectedly long absence. I built up a lot of inertia over all that time, so I’m glad to finally overcome it.
I did hit a snag related to my laptop’s Ubuntu installation; this results in me not being able to run the 3to2 tests right now. I’ll just commit what I have (the recent change probably does what I think it does, but it’s disabled by default so that it doesn’t bother anyone) and work through this tomorrow. Shouldn’t take more than a few minutes when I’m fully awake, but I’ve learned from experience that I shouldn’t try to do significant sysadmin stuff this late at night if it’s not time-critical.
