What is the best way to count iterations in a foreach loop? Usually, if I need to count iterations, I'll just increment a variable each time through - something like 
$i = 0;
foreach (@array) {
    # do stuff
    $i++;
}

Is there a better way to do this? Maybe through one of Perl's special variables? I thought about searching for the array index containing the current value (like, "what is the index of @array that contains $_"). Also, I'm not necessarily looking for a solution to give me a total end count of iterations, but more for telling me how many iterations I have gone through so I can say things like "print this line every 3rd time through the loop"
