in thread How would you rewrite this?

Note that your code doesn't follow the original with regard to the index. You only increase the index if the if branch is evaluated. You need to increase $i outside the if. I'd probably rewrite it to this though:

my @fields = qw/ ... /; for (0 .. $#fields) { get_updates($objects[$_], $fields[$_], $result_ref->{$fields[$_]} if defined $result_ref->{$fields[$_]}; }
A structure like that doesn't invite to get things out of sync.


See perltoc if you don't know which perldoc to read!
