Also, when the term first time was brought up here, it was pointed out that this technique has been used for quite a while, also before the book got published. However, now we have a name for it. :) Regards, Terje _______________________________________________ Unsubscribe & other changes: http://lists.boost.org/mailman/listinfo.cgi/boost
