Once you get into Hal you can gear axes, start and stop motion independant of any other axes, load distances to travel etc.
It is sort of a motion erector set. Very capable. I've done some things with it but I feel like I have only scratched the surface of it's capabilities. And then you can expand it by writing your own Hal components on top of that! Classic Ladder links into Hal quiet nicely.
