[[Property:title|Removing object while iterating on a LIST]]
If you already have the object that you want to remove from the <code>LIST</code> you can easily use <code>prune</code> and <code>prune_all</code>. But if you want to remove objects while iterating on that <code>LIST</code>, depending on criteria on the objects contained in the <code>LIST</code>, here what you can do.
First of all, if you think about removing object while iterating, I do not recommend using an <code>across</code> loop. If you iterate on the list using a <code>from until loop end</code>, just remember to use the <code>LIST.forth</code> only when you do not use <code>LIST.remove</code>.
