Then you can use 'for(my $i = 0; $i < @array; $i++)'. In your example
above, you are incrementing $i twice (first postincrement, then
preincrement). It doesn't make sense (to me, at least) to have an index
counter, and then still assign the array element to a temp variable.
Just loop through the array with the counter and use the array directly.
