title: Accessing a Class' instance variable from outside
body: <p>I understand (I think) the difference between class variables and instance variables of a class in Ruby.</p>
  
  <p>I'm wondering how one can access the instance variables of a class from OUTSIDE that class.</p>
  
  <p>From within (that is, in a class method instead of an instance method), it can be accessed directly, but from outside, is there a way to do <code>MyClass.class.[@$#]variablename</code>?</p>
  
  <p>I don't have any specific reason for doing this, just learning Ruby and wondering if it is possible.</p>
