Isn't this primarily a QoI thing? If your compiler issued a "Warning: if-statement misses controlled statement (extra ';' ?)" would you still want the null-statement deprecated? I commonly write catch (Ex) { ; } and I think it's clear what this does; I don't think this usage should be deprecated. Regards, -- Michiel Salters --- [ comp.std.c++ is moderated.
