The implementation is fine, AFAICT. The only problem with me is the comment:
I couldn't understand it for the first time because "none *it" sounded
confusing. Maybe "*it is never equal to u" is better?
BTW, if you could sumbit unified diff instead of new implementation, that
would be nice. If that's not convenient for you, no problem. I can apply
the thange anyway.
Thanks,
