-- Module:Item link
--
-- This module implements Template:Item link.
--
-- This is separate from the main item module for small speed ups. Those speed
-- ups are only sigificant if the module is called a lot of times (100+), in
-- tests this amounted to only a ~10% difference in page load times at best. It
-- should be noted those tests are difficult because of the large variance in
-- page load times.
