Just this week I ran into a situation where I needed to be more systematic in element removals. Reading the array section in Q&A proved to be enlightening. Note the use of splice here.

Quoting from the Q&A

my $index = 0;
while ($index <= $#items ) {
  my $value = $items[$index];
  print "testing $value\n";
  if ( $value == 1 or $value == 3 ) {
    print "removed value $value\n";
    splice @items, $index, 1;
  } else {
    $index++;
  }
}

I tried using delete (which I thought was just for hashes) but got zero results, though the Perl ref says it's one of the methods. But maybe I'm not quite getting it.
