Comment (by dd32):

 > But I still can not see how that should apply to $wp_query->comments (I
 didn't get it filled in my test script either, just asking).

 If you tested on a page which might possibly have it set, you'd find it's
 an array of references to arrays.

 For readability, I'd prefer to have the output list separate from the
 input list, rather than just juggling PHP reference's.

 The other thing which this will protect against is a reference to an array
 being passed in to $list, which while deprecated in PHP (Call-time pass-
 by-reference) some developers may still do.
