This works already now:
def quicksort(array, start, end):
midp = partition(array, start, end)
if midp <= (start+end)//2:
quicksort(array, start, midp)
return quicksort(array, midp+1, end)
else:
quicksort(array, midp+1, end)
return quicksort(array, start, midp)
It might even be tail-call optimized by Python. Only you can't count on
it because the language spec doesn't guarantee it.
