So I thought that if I did...

extends Node
class_name MyClass #as a kind of namespace

extends MyClass
class_name SubClass
const MyDir = {MyKey=MyVal}

I would be able to assign MyVal like...

var SomeVal = MyClass.SubClass.MyDir.MyKey

that doesn't work 🤔 but this does 😅

var SomeVal = SubClass.MyDir.MyKey

I wanted the class > subclass hierarchy but for ocd reasons but maybe I should just not and just name the subclass namespace_subclass

Naming things is hard.
