------- Comment #21 from paolo dot carlini at oracle dot com  2009-07-27 09:34 -------
Thanks Jason. I'm tentatively recategorizing as libstdc++, then. In general,
I'm not at all sure what we should do about it, however, now that Concepts are
gone. I don't think we can hope to avoid, here and elsewhere, all the typical
problems caused by unconstrained templates. Certainly, having the two separate
overloads:

  template<typename InputIterator, typename Distance>
    InputIterator next(InputIterator, Distance);

  template<typename InputIterator>
    InputIterator next(InputIterator);

would lead to cleaner error messages in case of ambiguities, but I'm not sure
we can in general achieve much more than this.
