Which is why CPS.pm documents them thus:
=head2 kforeach( \...@items, \&body, $k )
CPS version of perl's foreach loop. Calls the body code once for each element
in @items, until either the items are exhausted or the body invokes its $klast
continuation, then invoke $k.
$body->( $item, $knext, $klast )
$knext->()
$klast->()
$k->()
=cut
