The second piece of code will basically match all the nulls and put them into an anonymous array and then put the size of that array into $nulls. From a couple of tests I did using Devel::Size, an array with half a million nulls will take up about 320 MB. If you go any larger, this will quickly exhaust memory on a standard computer.
