On light aircraft the POH often says to get the nose off the ground as early as possible when performing a takeoff on soft ground. From the Piper PA-28 handbook:
Takeoff from a soft field with obstacle clearance requires the use of 25 degree flaps. Accelerate the airplane and lift the nose gear off as soon as possible and lift off at the lowest possible airspeed.
I think that this would result in some of the takeoff run being performed with the wing stalled.
At the other end of the spectrum, you've got the Concorde. If I remember correctly it was technically in an aerodynamic stall for both takeoff and landing.
