I can easily see people using that same statement to argue for all sorts of rules about "using namespace std" (always, never, sometimes) > Bottom line: I'd agree to a rule to avoid using directive and > declarations in header files, but please don't stigmatize "using" as an > intrinsically bad thing. I think everyone agrees on not using it in headers, and with David's suggested guidelines it seems it would be fine to use in implementation files for nearly every C++ program in FreeBSD's base system (we're not going to use boost in base utilities). -- John Baldwin _______________________________________________ svn-src-head@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/svn-src-head To unsubscribe, send any mail to "svn-src-head-unsubscr...@freebsd.org"
