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).
