In Perl, is there a built in way to compare two arrays for equality?

compare

I have two arrays of strings that I would like to compare for equality:

my @array1 = ("part1", "part2", "part3", "part4");
my @array2 = ("part1", "PART2", "part3", "part4");

Is there a built-in way to compare arrays like there is for scalars? I tried:

if (@array1 == @array2) {...}

but it just evaluated each array in scalar context, and so compared the length of each array.

I can roll my own function to do it, but it seems like such a low-level operation that there should be a built-in way to do it. Is there?

Edit: sadly, I don't have access to 5.10+ or optional components.
