in reply to Foreach Loops

You can have a counter: 
my $i = 0;
foreach (@myarray) {
  # stuff goes here
  $i++;
}

A slight improvement over holli's in that you can access the entire i-1 previous elements.

    You should really put the counter increment in the continue block, though, in case of next or redo. Compare: 
    my @arr = ('a'..'m');

my $i=0;
foreach (@arr) {
  # stuff goes here
  next if $i%4 == 0;
  print "$i: $_\n";
}
continue { ++$i }

$i = 0;
foreach (@arr) {
  # stuff goes here
  next if $i%4 == 0;
  print "$i: $_\n";
  ++$i;
}
