Since chained mutators are not likely/easy/robust in Moose, I need to find a similar tool which does support things like below: 
 use Mouse;
 has 'body' => (is => 'rw');
 has 'hdr' => (is => 'rw');
 has 'ftr' => (is => 'rw');

 1;

 my $m = Doc->new;
 $m->body('double')->hdr->('headless')->ftr('soccer');

It appears that Fey has some technology like this under the hood based on the synopsis example: 
 $select->select( $user->columns( 'user_id', 'username' ) )
         ->from( $user, $group )
         ->where( $group->group_id, 'IN', 1, 2, 3 )
         ->and  ( $func, 'LIKE', 'smith%' );
