This crates a conflict with range/join.hpp which defines boost::join directly. If I want to use both in one compilation unit, I have to wrap one of them in a separate class --> ugly. Suggested fix: I do not think that ""using algorithm::join"" is needed in the file algorithm/string/join.hpp." Bugs new To Be Determined algorithm Boost 1.46.1 Problem
