By itself it's not enough to keep romberg and quanc8. I don't think
we want to tell people, "You can simply nest the numerical integration
calls if you're OK with using methods which don't work so well."

Quoting the inner call yields the same result with quad_qags --
quad_qags ('(quad_qags (x^2 + y^2, x, 0, y)[1]), y, 0, 1);
  => [.3333333333333333, 3.70074341541719E-15, 21, 0]
