before overload
to overload
to overload
after overload:
overload1
overload2
0rasputin@lb:rasputin$ expand -t2 dyn.rb 
class Test
  def msg
    puts 'to overload'
  end
end

t1 = Test.new
t2 = Test.new

puts 'before overload'
t1.msg ; t2.msg

class << t1
  def msg
    puts 'overload1'
  end
end

class << t2
  def msg
    puts 'overload2'
  end
end

puts 'after overload:'
t1.msg ; t2.msg
