I noticed while working on #2361 that
instanceCanallows any string as a key, which means you can doinstanceCan.detaaaaaach(instance)and not get a type error. The goal here was to make that a type error without affecting the API, so we don't have to change any call sites.After some back and forth with myself around several ways one could make this work, I landed on this, which is more verbose than I prefer, but it's fine.I did it.Rather than try to explain the other stuff I tried, here is a fun and exciting video of me suffering.
