<ul> <li>jackdied: Does your class have two methods, one of which is `init`?</li> <li>veky: errrm... no? :-)</li> </ul> (<a href="https://youtu.be/o9pEzgHorH0?t=180">context</a>)

Liked the video. There is a bit of work in the `init` and it comes with a few useful (named) attributes so it's fine for me. Yep, I came here thanks to the weekly mail I told you about.

Yes, in fact my class is not one of those Jack warns us about. But it's funny that it doesn't even have two methods. :-D <hr /> And do you see that it works even with many days skipped, not just one? (Also `RecursionError`-proof, since `365<sys.getrecursionlimit()`;)
