The occurence of boost::io::put in the above example has to be qualified, since otherwise it will refer to the member function being defined.
What I have to say has nothing to do with namespaces or directory placement, but...
Given that in the documentation you speak of user-defined overloads of boost::io::read et al, it might be worthwhile to point out that two-phase lookup will not see these user overloads. If you want to have an overload customization point in a template, you have to use an unqualified call. And choose the identifiers wisely. :-)
Of course, overloading isn't always the best approach (it introduces nasty ADL and complicated resolution rules), so consider using a static member of a class template that can be specialized, instead. -- Dave Abrahams Boost Consulting http://www.boost-consulting.com
