What is missing is the ability to use each on an array. It would work like this:

   my @array = qw( foo bar rat );
   while (my ($val,$idx) = each @array) {
      say "$val at $idx";
   }

   # produces

   foo at 0
   bar at 1
   rat at 2

Sometimes it's really nice to have both the value and index at once. Nicholas Clark had this up and running in bleadperl a few months ago, but the pumpking judged that it was regretfully a far too major change in the syntax to hold up the release of 5.10

There is discussion about how to retro-future-fit it into the 5.10 maintenance track, so as to avoid a full release cycle that would require waiting for the first 5.12 release.
