At least they managed to kill `auto_ptr`.

Turns out, these two are equivalent in practice (but UB in the C++ standard):

    double solve(double a, double b, double c, double d) {
      return a + b + c + d;
    }

    double solve(double a ...) {
      return a + 1[&a] + 2[&a] + 3[&a];
    }

I guess that's a preview how C++ require a lifelong commitment.
