 ## Thoughts
 
 - We should have a way to not copy components on deferred spawn/clone
-- Not all assoc_list_remove operations need to keep order, we can have an unordered variant also
-- We still have several places where we use __lua_next without deterministic order, we should fix that
 - Having a light version of the gargabe collector can be useful for some use-cases
 - We can shrink the table pool tables on garbage collection if they are too large
-- Should we sort chunk children by fragment id?
 - Basic default component value as true looks awful, should we use something else?
