Hi! I often bump into a problem having the following gist: -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= view nodes: #( $a $b $a). view edgesFromAssociations: { $a -> $b . $b -> $a} -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= How can I express the the second $a and not the first when defining edges? I have the impression this limitation comes from the fact that two different nodes have the same model behind ($a), and there is no way to distinguish between them. An easy and backward compatible solution would be to permit to provide nodes: -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= nodes := view nodes: #( $a $b $a). view edgesFromAssociations: { nodes first -> nodes second . nodes second -> nodes third } -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Opinion?
