Re: Why is there no combination of popFront and front to pop? (aka Python `next`)

[Ali Çehreli via Digitalmars-d-learn]

Sorry, this is the rest of the program: :)

struct S {
    int i;
    static size_t copyCount;

    this(this) {
        ++copyCount;
        if (!(copyCount % 2)) {
            throw new Exception("Failed to copy S");
        }
    }
}

auto next(Range)(ref Range a){
     auto b = a.front;
     a.popFront();
     return b;
}
