lib nested modules name space clash with models on console (bug or feature?)

given an AR class like Facility on ./app/models/facility.rb

and a namespaced module in a library with the same name ./lib/extensions/facility.rb
when invoking the Facility constant class name from console

AS loads first the file under the lib, not the model definition class

app/models/facility.rb

class Facility < ActiveRecord::Base
end

lib/extensions/facility.rb

module Extensions
module Facility end end

rails console Loading development environment (Rails 3.0.6)
ruby-1.9.2-p136 :001 > Facility
LoadError: Expected /home/andres/Documents/code/sage/lib/extensions/facility.rb to define Facility
