This allows for better constant management. Use it like so:
  class MyClass
    set_const :read, 1
    set_const :write, 2
  end

You can then reference it directly like so:

  MyClass::READ

Unfickle gives you the ability to traverse through your constants by calling 
  MyClass.each_constant {|constant,constant_value| dosomething(constant, constant_value) }
