I do not believe Ruby does not give you direct external access to variables.
Everything with a ‘.’ is a function call.
You would use e.g.
Foo.new.instance_variable_get("@bar”) // => 5
attr :bar exposes a variable @bar through functions bar() and bar=() (and
also optimizes storage in some implementations)
