The -320 is not an exotic airplane and it does not have relaxed stability. It stalls just like any other airplane with all the magic off.
I had the chance to fly with the late Nick Warner and we visited the handling with all the magic off. As Nick said, "When everything goes down we are not going to fold our hands and say, 'thank you for a very nice life.' We still have options."
FWIW, I also had the opportunity to stall the 737-300 in clean and dirty configs. The first indication was a buzz which developed into a rumble and then a distinct and noticeable vibration as if the airplane was saying, "Do you really want to do this??" With the stall, the nose fell through; I released back pressure and added thrust to recover. Straight forward and simple.
