`You can remove the IIFE` is unsafe

[AlexXanderGrib]

Code:

function tick() { /* works with canvas */ }

(function loop() {
  tick();
  requestAnimationFrame(loop);
})();

p42 suggests to remove IIFE and deems it safe. Result:

{
  tick();
  requestAnimationFrame(loop); // So loop is undefined
}

Thanks for the bug report!

Starting in v1.147.2, remove IIFE is not available any more when there are self-references to the function. Please re-open if the bug still occurs.
