note hardburn <p>That's a nice solution, but is there any particular reason to use an arrayref rather than a scalarref? It'd make the iterating code just a bit cleaner:</p> <code> while( my $next = $iter->() ) { $next = $$next; ... } </code> <p>As opposed to:</p> <code> while( my $next = $iter->() ) { ($next) = @$next; ... } </code> <!-- Node text goes above.
