Loch Ness Monster Case implementation in Ruby

lochness.rb

class String

  def loch_ness_monster_case
    self.split('::').collect do |section|
      section.gsub(/([^\/])([A-Z])/, '\1_\2').downcase.split(/_/).collect { |part|
        chars = part.split('')
        half  = chars.length/2
        chars[half].upcase!
        chars[half - 1].upcase!
        chars.join('')
      }.join('_')
    end.join('/')
  end
  alias :nessy_case :loch_ness_monster_case

end

if __FILE__ == $0
  require "rspec"
  require 'rspec/autorun'

  describe "String#loch_ness_monster_case" do

    it "works!" do
      "LochNessMonsterCase".loch_ness_monster_case.should == 'lOCh_nESs_moNSter_cASe'
      "loch_ness_monster_case".loch_ness_monster_case.should == 'lOCh_nESs_moNSter_cASe'
    end

    it "works with modules!" do
      "Monsters::LochNessMonsterCase".loch_ness_monster_case.should == 'monSTers/lOCh_nESs_moNSter_cASe'
    end

  end
end

+1, though I'd like to see an alias to nessy_case -- I've forked to support this: https://gist.github.com/1996344

nessy_case - perfect! brought it in here :)

Can we have a PHP implementation please? It would be a perfect addition to the many different cases already in use :)
