That's not a problem I've run into, and I don't see it cropping up all that often on c.l.py. (To be precise, I don't have any memories of it cropping up.)

No, most search loops you see on c.l.py don't bother with this at all, and are brittle as a result. That's the point. The need for additional "thing is None" kinds of clauses is something people learn the hard way, after they've been burned by making a bad guess for an extreme initial value (or more likely what turns out to be bad eventually -- passes all their initial tests, but screws up later when input changes).
