This looks OK, and I think it fixes all the cases we have currently,
but it doesn't cover every case one may write (like a multi-line
attribute), i.e. I was wondering whether the complexity of this is
worth it or not (especially if later on we try to support every case).
But it may be that never happens, or happens way less often than even
this case that we may not even care.

By the way, why `saturating_sub` in particular? I guess because of
underflow, but can that happen? And if it can (perhaps in a future
compiler version), wouldn't we want to notice?

Thanks!

Cheers,
Miguel
