An alternative would be to return None for not found. It wouldn't solve the problem of people using the return value as a boolean, but at least you'd get an exception if you tried to use the not-found value as an index.
Or maybe it could return index values as a special int subclass that always tests true even when it's zero... How about returning a str.NotFound object?
Whoops, scratch that, doesn't solve anything more than returning None.
