They're perfectly counter-intuitive for use in "rotate" though:

    // trying to express that I intend to rotate by 45 degrees,
    // with the effect of rotating by 45 radians instead
    rotate x * degrees(45)

    // trying to express that I intend to rotate by 0.3 radians,
    // with the effect of rotating by something particularly useless
    rotate y * radians(0.3)
