I'm very impressed how you wrote it off the top of your head :-> But it's definitely too much magic. Though, it made me think of another magic: study alloca implementations and replace a global variable with something like BOOST_SCOPE_EXIT( (hello)(world) ) // line 1 /* Expands to: struct args_line1 { std::string &hello, &world; } args_line1 = { hello, world }; void** saved_args = (void**)aloca(sizeof(void*)); *saved_args = &args_line1; struct scope_exit_line1 { void* m_args; ~scope_exit() { struct args_line1* p = (struct args_line1*)m_args; doit(p->hello, p->world); } static void doit(std::string& hello, std::string& world) */ { // scope(exit) code } BOOST_SCOPE_EXIT_END // line 5 /* } scope_exit_line5 = { *static_cast<void**>(last_alloca_result()) }; */ The key here is get_alloca_result that returns a value returned by last alloca call. -- Alexander Nasonov http://nasonov.blogspot.com When you`re comfortable with someone you love, the silence is the best. -- Britney Spears -- This quote is generated by: /usr/pkg/bin/curl -L http://tinyurl.com/veusy \ | sed -e 's/^document\.write(.//' -e 's/.);$/ --/' \ -e 's/<[^>]*>//g' -e 's/^More quotes from //' \ | fmt | tee ~/.signature-quote
