"According to the operating handbook, the An-2 has no stall speed. A note from the pilot's handbook reads: "If the engine quits in instrument conditions or at night, the pilot should pull the control column full aft and keep the wings level. The leading-edge slats will snap out at about 64 km/h (40 mph) and when the airplane slows to a forward speed of about 40 km/h (25 mph), the airplane will sink at about a parachute descent rate until the aircraft hits the ground." As such, pilots of the An-2 have stated that they are capable of flying the aircraft in full control at 48 km/h (30 mph) ... This slow stall speed makes it possible for the aircraft to fly backwards relative to the ground: if the aircraft is pointed into a headwind of roughly 56 km/h (35 mph), it will travel backwards at 8 km/h (5 mph) whilst under full control."
I'm sure this is a slight exaggeration in my memory, but it really was able to fly incredibly slowly and take turns in an incredibly short distance.
I wonder if there's anything else built that fits that market today, since I suppose it's a hard-sell to convince Western pilots and businesses to buy Soviet old-stock.
For An-2, the ability to perform such tricks wasn't really the goal, just a side effect. The goal was to have a cheap mass-produced utility plane that could take off and land on very rough makeshift airstrips in remote locations, which were plentiful in USSR at the time when it was designed (~1950). These days there's probably way fewer locations like that, and for those that do exist, helicopters provide an adequate solution without the need to design a new dedicated airframe. Note that all those benefits aren't free, either: the downsides of the design include high fuel consumption and high noise levels.
As far as I know, even in Russia, most present-day use of An-2 is for skydiving.
It would be a neat trick to see a pilot pull that off intentionally and under control.
