Subject: More than one initializer

Hi all,

I have a module containing two classes the first is 'item' the second is
'search'. Lets use twitter as an example:
module MyTwitter
  class Item
    attribute_reader :id, :tweet
    def initialize(text)
      @tweet = text
      # Post to twitter
      @id = id_from_post_operation
    end
  end

  class Search
    def self.do(q)
      # perform search
      out = []
      results.each do |hit|
        # This is the problem point:
        out << Item.new_from_data(hit.id,hit.text)
      end
      return out
    end
  end
end

When I create a new Item object I have code that creates a new tweet
however I'd like my Search to return an array of Item objects, but if I
use the standard MyTwitter::Item.new I'll be posting a new item,
not simply creating an object with the id I have from my search.

Is there a way to create an object with a given attribute without
calling .new?

I hope I've explained myself well enough! Thanks,
JP
