Strange that I never noticed that.  I remember when 2.022 came out, I did 
not see it there, but I guess I could have overlooked it.  It definitely was 
not there when 2.021 came out (I remember many people asking for docs on it, 
including myself).

One question, it mentions that you must define all 5 properties.  In the 
case where you are only going to use foreach (and not foreach_reverse) on a 
struct, is it still required that you implement toe and retreat?  If not, 
then that probably should be mentioned in the docs.
