ya much the same functionalilty but it would be nice to have the %feature[0] however maybe the reason he hasnt implemented it is because that is a valid variable name and it might break several scripts? not sure havent chekced and too lazy to but does the parser allow [] in variable names if so.... maybe thats why...
however he could still do like $array(%feature,0) $array(%feature,1) etc just for backwards compatibilities sake and not breaking any scripts woudl used [] in variable names this is of course assuming you can...
Just a thought
