Hello all, *TLDR: Why doesn't RandomAccess interface extend List?*
I'm maintaining a framework that lets developers build plugins, and developers implement a `put(List<Thing> thingList)` in their plugins. However, I want to guarantee to the implementer that their List will support RandomAccess. I see Java does support a syntax for declaring that the argument should implement both List and RandomAccess using the "&" operator, and I could declare my own interface that extends both, but I am surprised that RandomAccess itself does not extend List and appear in the List hierarchy. According to the docs, it only applies to List implementations anyway, and we use `instanceof` extensively in the code to bifurcate how we handle both cases. It seems more natural to me for RandomAccess to extend List, so that I can let my implementer know explicitly they can rely on RandomAccess. I am happy to give more details on my scenario, and very excited to learn more why this decision was made, and if there is an aspect I am missing or if improvements could be made! Best wishes, Cyrus
