break is a standard c++ keyword already. Yes, BOOST_BREAK should be used instead
Also I don't understand what problem this solve.
Exiting from nested loops is something that could be quite complex using structured programming. Named blocks try to make more structured a goto based solution, by allowing only to restart/leave a block from inside it. BOOST_NAMED_BLOCK(L) for(;;) { while (cnd) { if (cnd2) BOOST_BREAK(L); // go to [1] } } // [1] Of course in order to be really structired the jumping to the underlying label should be forbiden (by the compiler), but I don't think that a preprocessor solution could take care of this. So the following not desired and not structured code could compile even if we would like an compile error. BOOST_NAMED_BLOCK(L) { // ... } // [1] //... BOOST_BREAK(L); // go to [1] HTH, Vicente
