The arrow operator passes the thing on the left to the function on the
right, so
CLASSNAME->method();
is the same as
CLASSNAME::method("CLASSNAME");
Given that you imported the sum function, you should just say
my $lks = sum @lk;
If you don't want the sum function in your namespace (for instance if
you have your own sum function that behaves differently), you should
say
use List::Util;
my @lk = (12, 3, 8);
my $lks = List::Util::sum @lk;
