I am adding elements of multiple arrays together and creating a new array with the sum. I was curious to know if there was a perlish one-liner type way of doing this. Here is how I'd do it using a loop:
# using a loop
@foo = qw(1 2 3 4);
@bar = qw(1 2 3 4);

for ($i = 0; $i < 4; $i++) {
    $foobar[$i] = $foo[$i] + $bar[$i];
}

# @foobar is now (2 4 6 8).

I have no problem doing it that way, but I was just curious. One day I may need to do this to more than two 4 element arrays and I won't want to type all that =)
