on 5.5 kamailio wiki for core it is stated that return (0) is the same as exit. but that's not true

request_route {

    if (route(POS)){
        xlog("POS PASS\r\n");

    if (!route(NEG)){
        xlog("NEG PASS\r\n");

    if (!route(ZERO)) {
        xlog("ZERO PASS\r\n");

    xlog("AFTER ZERO\r\n");

    return 1;

    return -1;

route[ZERO] {
    return 0;

for example from the config above not only ZERO PASS will be printed but also all the actions after route(ZERO) are still executed.

instead if i replace return 0 with exit in route[ZERO]. this work as expected.
