Need to be careful with this - the original search proposal returned a
list, which could be tested for a boolean value - hence:

    if not string.search(sub):
        pass

but if an iterator were returned, I think we would want to be able to
perform the same test i.e. search would have to return an iterator that
had already performed the initial search, with __nonzero__ reflecting
the result of that search. I do think that returning an iterator is
better due to the fact that most uses of search() would only care about
the first returned index.
