Style: do not defensively use `saturating_sub()` Using `saturating_sub()` here in code which cannot fail brings a false sense of security. If for any reason a logic error was introduced and caused `self.loop_depth` to reach 0 before being decremented, using `saturating_sub(1)` would silently mask the programming error instead of panicking loudly as it should (at least in dev profile). changelog: none

Fun fact, I force-pushed (with only a new commit message, content unchanged) after you r+'d it. I guess bors will keep the previous one, which is fine. |

The force push might have confused bors 🤔 |
