Re: [drupal-devel] Improve Drupal themability

We already have theme_item_list(). If you need more features from it, please submit a patch.

about theme_status_messages(), theme_node_list().

theme_node_list() and theme_user_list() are useful wrapper functions for theme_item_list(). They are useful because the themer themer knows what type of data he is dealing with and can universally style accordingly. Consider prefixing all blog posts with a special icon, or prefixing every user with an online/offline indicator. That is easy to do today but would be hard if you you go to a your proposed scheme.
