I was sort of expecting WP 2.3 would include helper functions and conditional tags for the new tagging system. Things like is_tag() to determine whether the current page is a tag archive. Also a function like get_the_tag or something like that for getting the tag in question.
The reason I'm asking about this is that I'd like to design the tag loop page to show a title of "Tag archive for ..".
Are those functions planned for another WP iteration?
