I want to make a simple Vector struct class:

struct Vector {
    alias _data this;
    alias data!0 x, width;
    alias data!1 y, height;

private:
    @property float data(int i)() {
        return _data[i];
    }

    @property void data(int i)(float value) {
        _data[i] = value;
    }

    float[2] _data;
}

But I get two similar errors:
Vector.data matches more than one template declaration, vector.d(9):data(int i)() and vector.d(13):data(int i)(float value)

I see that it might cause problems to have ambiguous aliases, but does anyone know how I might implement this? Should I remove the struct and just make @property x for float[2] and the others?

    template data(int i) {
        @property float data() {
            return _data[i];
        }

        @property void data(float value) {
            _data[i] = value;
        }
    }
