Since I see Larry Garfield has looked at this list today, I thought I would ask this now since I just had this come up.
 
I know about the new ":label" for substitution in D7 and have no problem with that. But what do I do with an array of values, as in:
  $types = variable_get('my_types_list', array());
  $args += $types;
  $result = db_query(..., $args);
 
Yes, I properly used db_placeholders to set the "%s" values in place. The query works fine in D6, it's just that I am already looking at teh upgrade and wondered about how to do arrays of values like this, when I can't go in and add a label to them.
