ça vaudrait le coup de regarder dans contrib si il y a pas des trucs a réutiliser plutôt que de les redéfinir je pense en particulier a Class Or Trait ou a Hierarchy

genre https://github.com/scalameta/scalameta/blob/master/scalameta/contrib/shared/src/main/scala/scala/meta/contrib/TreeOps.scala#L58 pour hierarchy .. ?

Bonne idée. Maintenant que cela fonctionne, je vais essayer de simplifier mon code.
Merci pour l'info
