  # ==Summary
  # Constantize tries to find a declared constant with the name specified
  # in the string. It raises a NameError when the name is not in CamelCase
  # or is not initialized.
  #
  #
  # ==Examples
  #     Helpers.constantize("Module")   #=> Module
  #     Helpers.constantize("Class")    #=> Class
  def Helpers.constantize(camel_cased_word)
    unless /\A(?:::)?([A-Z]\w*(?:::[A-Z]\w*)*)\z/ =~ camel_cased_word
      raise NameError.new("#{camel_cased_word.inspect} is not a valid constant name!")
    end

    Object.module_eval("::#{$1}", __FILE__, __LINE__)
