Jumping from a scope

Question

Is it possible to jump from an unnamed scope?

void MyFunc() {
    {
        ... // Code

        if (!head_size) {
            goto _common_error; // <- break and continue don't work here
        }

        ... // Code

        if (!tail_size) {
            goto _common_error; // second time
        }

        ... // Code
    }

    _common_error:
    {
        ... // Code
    }
}

My question is not whether this can be redesigned, but whether there is a trick in c++ that I don't know.

Is there a mechanism in c++ other than goto to jump out of an unnamed scope? break and continue do not work in scopes.

Update1: changed word namespace to scope

Answer 1

Yes, you need to use goto to jump out of a scope.

break can only be used to jump out of a loop or switch.

But you can use a (questionable) trick by using a dummy loop:

void MyFunc() {
    do {
        ... // Code

        if (!head_size) {
            break;
        }

        ... // Code

        if (!tail_size) {
            break;
        }

        ... // Code
    } while (false);

    {
        ... // Error handling code
    }
}
