>>>>> To be fair, having @root (from class Foo) == foo.root, where "root" in class Foo does *not*, is somewhat counterintuitive. I think it's a most excellent thing, but it does lead to confusion among those learning about attr_* useage. <<<<<< Honestly, it’s not really counterintuitive unless you expect a variable to magically become an attribute, and frankly if they did, that would be _more_ confusing. Again: `root` is just a variable. It’s private to the object. `@root` is an attribute, which _can_ be public to the object. If you have a basic understanding of what a class is and what an attribute is, then this is the easy bit.
