I am not sure what all this talk regarding stalls means
in order to determine any airplane's behavior I was told to go to sufficient altitude and then determine at which point the airplane loses lift, then multiply that for 1.3 and that is your safe approach speed 
when lift is lost a stall is incipient, imminent in transit, developing beginning call it what you like its a stall
when you land you use the vref of 1.3 to attain safe maneuvering to land but once in the landing mode to achieve a satisfactory landing one needs to be close to the ground and achieve a "stall" if landing in a taildragger to get a 3 point landing which is the safest since that is the slowest speed possible
the exceptions are the IV-P and heavy irons airplanes that do not behave well at vref
but even in the iv-p when landed right I get my AOA to indicate a stall condition imminent
so every landing is a controlled stall
if you do not know what a stall is and at what speed it comes and how the airplane behaves when entering it then the message is clear: go play golf and forget about flying (b eware of lightining...)
