For a better way, see the Boost.Lambda library. Or you can use the indirect iterator adaptor from the boost sandbox (boost/iterator/iterator_adaptors.hpp) bool find(const std::list<boost::shared_ptr<A> >& Alist, int v) { return std::::find_if( , make_indirect_iterator(Alist.begin()) , make_indirect_iterator(Alist.end()) A(v)) != Alist.end(); } -- David Abrahams [EMAIL PROTECTED] * http://www.boost-consulting.com Boost support, enhancements, training, and commercial distribution _______________________________________________ Unsubscribe & other changes: http://lists.boost.org/mailman/listinfo.cgi/boost
