[wp-hackers] Comments outside the main loop

[Otto]

What you've overlooked is that $comments is not setup until you
actually get to the comments.php file.

comments_template() does more than just include comments.php. It
actually get the comments from the database, builds the $comments
array, and *then* includes comments.php.

So until you call comments_template(), $comments is empty.
