@@ -16,7 +16,6 @@ Next:
 * make it easier to hook into the type system and describe how to do that to eg auto-generate meta types on first use
 * review multi component views to reduce instantiations once empty types are gone...
 * add observer functions aside observer class
-* registry clear can use the range-destroy and run much, much faster!
 
 * WIP:
  - introduce the component iterators for non-contiguous collections of entities (multi component views, observers, user defined collections)
