Yes, BOOST_BREAK should be used instead

Exiting from nested loops is something that could be quite complex using
Named blocks try to make more structured a goto based solution, by
allowing only to restart/leave a block from inside it.
if (cnd2) BOOST_BREAK(L); // go to 
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
BOOST_BREAK(L); // go to
