18:31 < anoe> when you are on a node suppose a List, maybe you want to merge data from another node list

18:32 < anoe> so seeg implemented the tree already

18:32 < anoe> such tree (as fork on the Tree you know) enables the capability to select another node

18:32 < anoe> and launch whatever function you need with the nodeid that is selected

18:33 < anoe> so the idea, is having the capability to use such tree elsewhere to select a parameter of a function
