Finally I found some time to try things and I answered myself. Just in case anyone find this useful I'll put a link to the post I wrote explaining how to use lazr.delegates to improve the infoheritance pattern found in the Storm documentation: <a href="http://www.lorenzogil.com/blog/2009/01/18/mapping-inheritance-to-a-rdbms-with-storm-and-lazrdelegates/">http://www.lorenzogil.com/blog/2009/01/18/mapping-inheritance-to-a-rdbms-with-storm-and-lazrdelegates/</a> I hope it's useful Lorenzo <div class="gmail_quote">2009/1/15 Lorenzo Gil Sanchez <<a href="mailto:lorenzo.gil.sanchez@gmail.com">lorenzo.gil.sanchez@gmail.com</a>> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Hi, I just saw that Canonical has open sourced a package called lazr.delegates[1] and I think that one of its possible uses may be about hiding the composition stuff that the infoheritance does and make it all looks like real inheritance. I wonder if anyone one has working code that uses both things and is willing to show it to us since I'm really interested in them for my application. As I still need to make my brain used to these concepts some tutorial or examples would really help me.
