Can't create global read marks if a model is both reader and readable

[caffeineshock]

If have a model like the following

class User < ActiveRecord::Base
  acts_as_reader
  acts_as_readable :on => :created_at
end

marking all instances of a model won't work. It seems that calling has_many with the same association. if I change the call of has_many in acts_as_readable to

has_many :read_marks_readable, :class_name => "ReadMark", :as => :readable, :dependent => :delete_all

all is well (if readable.rb is updated too, of course). Should I issue a pull request for that change? And if so do you have a good idea what to call the associations?
