You might also try writing a test case to help you figure out what the
expected behaviour should be and work towards it:

> cat KostasL.rb
require 'test/unit'

###/ Code Below \###

class A; end

class B; end

###\ Code Above /###

class KostasLTest < Test::Unit::TestCase
  def test_001
    a = A.new
    b = B.new

    a.set_reference(b)
    result = a.method1
    expected = "???"

    assert_equal(expected, result)
  end
end

> ruby KostasL.rb
Loaded suite KostasL
Started
E
Finished in 0.001412 seconds.

  1) Error:
test_001(KostasLTest):
NoMethodError: undefined method `set_reference' for #<A:0xb7c37550>
    KostasL.rb:16:in `test_001'

1 tests, 0 assertions, 0 failures, 1 errors

(So, an obvious next step would be to define a set_reference method in
class A; etc.)
