I wonder if there is a more elegant shorter way for doing some common array manipulation tasks:

  • swap two elements of an array
    • # swap $index1 and $index2 of @array
$temp=$array[$index2];
$array[$index2]=$array[$index1];
$array[$index1]=$temp;

  • step $index in direction $dir (+1 or -1) in array in a 'circular' way:
    • # step $index in $dir direction in @array circular
$index+=$dir;
$index=0 if $index>=@array;
$index=@array-1 if $index<0;
