I think what you want is a constant:

class Foo
  def initialize
    sc.const_set(:FOO, 42)
  end

  def foo
    puts sc::FOO
  end

  def sc
    class << self; self; end
  end
end

Foo.new.foo #=> 42

(I wish it were possible to use just FOO instead of sc::FOO, but
constant lookup in ruby is static).

I like Ara's method too.  I wouldn't have considered it.
