Boosters, I have read both the "Library Requirments and Guidelines" and specifically examined the "Boost Header Policy" and the section on naming consistency but have yet to understand how I should choose to use namespaces for the next version of Boost.Range, that incorporates the accepted Boost.RangeEx proposal. It feels indecent and naughty (in a bad way!) to be putting the library into the top-level boost namespace. More importantly I am concerned that general functions such as "find" will clash when combined with other boost libraries both now and in the future. Would the ideal scenario for new libraries be to have a library related namespace under boost in a manner akin to Boost.Filesystem? Is there already a strategy that is well-known that I am ignorant of? Is there an existing strategy to migrate libraries that pollute the top-level boost namespace that maximises backward compatibility? Any assistance with this matter would be greatly appreciated. Thank you in anticipation, Neil Groves
