(Needs to replace ... with range_iterator<T> variants, add non-const overloads, handle the old range_begin customization point) I don't see how that kind of thing can cause infinite recursion. If there is no overload of begin picked up by ADL, it uses range_detail::begin.
I see. I forgot about the default implementation. The problem with this scheme is that if boost is an associated namespace of T, then boost::begin will be ambiguous with boost::range_detail::begin. The workaround used by boost::swap doesn't work in this case.
I had kind of hoped that we could do the same thing as boost.swap. If not, that is really bad news. -Thorsten
