[stuff involving various tag_ names]
One mistake made in a lot of Boost documentation and discussion of Boost interfaces is the omission of namespace qualification, under the assumption that appropriate using declarations have been made. However, in practice someone is unlikely to make those using declarations, and in any case it turns a one line call to convert into a potentially 3 or more using declarations followed by a call to convert. Thus, I propose that any time a code sample is provided, it be in a form that legitimately might occur in an actual program, so that it is apparent whether the namespace qualification is going to render an apparently nice interface into an excessively verbose one. You propose that a bunch of tag_ names be used, but in practice they would likely have to be something like boost::convert::tag_, which would substantially reduce the benefits of any such change.
