 I have a need to query for multiple users by their nicenames. Right now, I
 do something like this:

 {{{
 // Get usernames
 $usernames = some_function_to_get_usernames();

 // Loop through usernames and link to profiles
 foreach ( (array) $usernames as $username ) {

         // Skip if username does not exist or user is not active
         $user = get_user_by( 'slug', $username );
         if ( empty( $user->ID ) ) {
                 continue;
         }

         // Some things...
 }
 }}}

 It would be great if `WP_User_Query` worked in the following ways:

 `__in`:

 {{{
 $users = new WP_User_Query( array(
         'nicename__in' => array( 'admin', 'john', 'paul' )
 ) );
 }}}


 `__not_in`:

 {{{
 $users = new WP_User_Query( array(
         'nicename__not_in' => array( 'admin' )
 ) );
 }}}

 ----

 The "nice" thing about this, is `user_nicename` is an indexed column, so
 these queries should be speedy and internally optimized by MySQL.
