Said so, done so...  Its not pretty.  I keep wondering why

server> ruby b.rb
singleton singleton_method_added
server> cat b.rb 
txt = "text"
class << txt
  alias old singleton_method_added
  def singleton_method_added(parent)
    puts "singleton #{parent}"
    alias singleton_method_added old
    undef old
  end
  def aa
  end
  def bb
  end
end
