Ok, I'm doing something like the following:

module FooBarHelper

  class << Foo::Bar
     # some instance methods, which reference class vars from Foo::Bar
  end
end

Then, in classes A and B I do "include FooBarHelper".  When I run this
I get "uninitialized class variable" errors for the Foo::Bar's class
vars.

So, to state my question again, how can I extend the functionality of
the Foo::Bar library (short of hacking it's source directly), while
still maintaining access to the class variables defined in Foo::Bar?
Is this even possible?
