I haven't tested this, but I think that will end up looking for

It certainly looks nicer. But it didn't break saving so I assume it
means something like "if not <some expression>" which expression
happens to be "<instance in self.deleted_objects>"
Agreed. And I did finally get a chance to test this in the interpreter
with the same result. There's gotta be some implicit action going on
that counts the 'in' as a whole expression, and not taking 'instance' as
an individual object, because my dusty algebra brain is kicking and
saying that without () to sort out the order, the 'not' should apply
only to 'instance'. I even looked it up in the docs and 'not x' has a
higher operator precedence than 'in', only feeding my confusion.Â

Your way is easier to read so I'll adopt it.
I've never seen it written out the way you had it, before.
I'll agree with that. ;-D
Now I think about it, I suspect your way (and now my preferred way)
might have been an innovation for Python 3?
