I don't see any need to extend the legal use of next/prior to anything else than iterators.
It was already legal for non-iterators. What made you think otherwise?
I considered the fact that it works/worked for non-iterators an accident
It's not. I wrote it; I meant the spec to say what it says and not impose an iterator requirement.
as the documentation only speaks about iterators and never bothers to mention non-iterators. Thus, the bug is IMHO that it's not explicitly documented that next/prior's first argument must meet the interator requirements.
Sorry, dude, I get final say on original intent, since it was mine. -- Dave Abrahams Boost Consulting www.boost-consulting.com
