In Ruby, when one tries to access an instance variable directly, which is
always private by default, the return value is nil until it has been
properly initialized. You can access instance variables using an accessor
on a class. In any case, I recommend that you get a copy of "Programming
Ruby" or "Programming Ruby 1.9" and read the section on "Scope of Constant
and Variables".
Good luck,
