How to Access a Ruby Class Variable From an Instance?

To access the value of a class variable (i.e. @@variable) from an instance of a class, you can create a getter instance method, for example, like so:

class Foo
    @@bar = "bar"

    def bar

a =
b =

puts #=> "bar"
puts #=> "bar"

As you can see from the example above, the class variable is accessible via class instances and have the same value shared across each instance.
