If you want to have a list, you can have it in addition to count:
   accumulate( $w: Whatever(...) from window:length( 10 ),
                        $count: count(1), $list: collectList( $w ),... )

although that would be redundant. But if you'd just need the (for
instance) sum, it would be useful.
  accumulate( Whatever( $x:x, ... ) from window:length( 10 ),
                        $count: count(1), $sum: sum( $x ) )

Note that this is a *complete* CE, beginning with "accumulate".
