This code splits an array in two. It seems ugly and long. Is there a better perl way? Not looking for golf, just looking to learn better idioms. Thanks! 
sub split_array_in_two {
    my (@x) = @_;
    return ([],[]) unless @x;
    my $n = (scalar @x) -1;
    my $m = int ($n/2);
    return ( [ @x[0 .. $m]], [ @x[($m+1) .. $n]]);
}
