Re: goto

[grauzone]

I'd prefer to have some kind of goto, which enforces structured 
programming. Something like:

double euclideanDistance(Range)(Range a, Range b, double limit)
{
    limit *= limit;
    double result = 0;
    foo: {
        for (; !a.empty; a.next, b.next)
        {
            enforce(!b.empty);
            auto t = a.head - b.head;
            result += t * t;
            if (result >= limit) break foo;
        }
        enforce(b.empty);
    }
    return sqrt(result);
}
