C#でC++のcinっぽいの

作った。

class cin {
    private static Queue<string> tokens;
    static cin () {
        string line;
        tokens = new Queue<string> ();
        while ((line = Console.ReadLine ()) != null) {
            foreach (var token in line.Split (' ')) {
                tokens.Enqueue (token);
            }
        }
    }
    public static implicit operator int (cin cin) => int.Parse (cin.tokens.Dequeue ());
    public static implicit operator string (cin cin) => cin.tokens.Dequeue ();

    public void Deconstruct (out cin o1, out cin o2) => (o1, o2) = (this, this);
    public void Deconstruct (out cin o1, out cin o2, out cin o3) =>
        (o1, o2, o3) = (this, this, this);
    public void Deconstruct (out cin o1, out cin o2, out cin o3, out cin o4) =>
        (o1, o2, o3, o4) = (this, this, this, this);
    public void Deconstruct (out cin o1, out cin o2, out cin o3, out cin o4, out cin o5) =>
        (o1, o2, o3, o4, o5) = (this, this, this, this, this);
    public void Deconstruct (out cin o1, out cin o2, out cin o3, out cin o4, out cin o5, out cin o6) =>
        (o1, o2, o3, o4, o5, o6) = (this, this, this, this, this, this);
    public void Deconstruct (out cin o1, out cin o2, out cin o3, out cin o4, out cin o5, out cin o6, out cin o7) =>
        (o1, o2, o3, o4, o5, o6, o7) = (this, this, this, this, this, this, this);
    public void Deconstruct (out cin o1, out cin o2, out cin o3, out cin o4, out cin o5, out cin o6, out cin o7, out cin o8) =>
        (o1, o2, o3, o4, o5, o6, o7, o8) = (this, this, this, this, this, this, this, this);
}

こんな感じに使う。

int N                      = cin;
string name                = cin;
(int A, string str, int B) = cin;

castをabuseすると治安の悪いコードが書ける。
