Re: print array of hashes

In this one record or in all records?

my $kids= scalar @{$rec[0]{kids}};

If you want the sum of kids in all records you just have to add a loop around that line:

my $kids;
foreach my $record (@rec) {
  $kids+= scalar @{$record->{kids}};
}

Maybe we should point out that `scalar` is not necessary in your case, because you already are in scalar context. -- Ronald Fischer <ynnor@mm.st>	[reply] [d/l] [select]

True as that may be, sometimes it feels more comfortable to be explicit about what you mean. For example (and let's keep it simple): `my $total_price = ($item_price * $item_quantity) + $shipping_cost` In that example the parentheses aren't necessary because multiplication already has higher precedence than addition anyway, but I feel it improves readability.
