Simple creation of new inflections in Rails 3 (or whatever uses ActiveSupport::Inflector)

new_inflection_generator_for_rails.rb

# In case you want to define a new inflection so you can call something like:
#
#   "masochistic son of a gun".leet   # => "m450ch1571c 50n 0f 4 9un"
#
# Do the following so that the requisite methods are injected into each relevant
# class/module:
#
#   NewInflection.register :leet do |word|
#     word.tr('aegilost', '43911057')
#   end
#
# and then it is also available via ActiveSupport::Inflector.leet('something').
module NewInflection
  def self.register(name, &proc)
    inflector = ActiveSupport::Inflector
    
    inflector.send(:define_method, name, &proc)
    String.send(:define_method, name, lambda { inflector.send(name, self) })
  end
end
