Ok, I'm breaking down on the subject because I just don't get it.
Why would somebody who writes a little CMS (like MovableType) need to implement a set of custom tags for their system? You know, stuff like:
<%MT echo $the-title %>
Why not just give the user direct access - something more like:
<?php echo $prefs['the-title'] ?>
Now, yes, I know, MovableType is not the best example of this since it uses perl as well, but I know of a few people who are doing this.
I just don't see a real reason for it except to try to lock out the user from using php tags - but then again, they still do allow this...but at the template level...so why bother with the custom tags anyways?
Ok, sorry, I hope this makes sense to anybody.

ps: Blogger does this too, but I can understand this since it's their servers doing the work, not just any users server.
