cummulative changes, all running ./perl -Ilib -e 'use Carp; 1' mem used at end total malloced 178232 234839 before the changes 178232 230735 moving pod to end 178232 230735 removing comments 178232 228575 removing pod 178023 226624 moving variable initialisations to Carp::Heavy 176330 224251 streamlining code So moving and removing the pod both affect the accumulated mallocs(), but don't affect the residual unfreed memory at process exit. The totality of these changes save somewhere between 2-10K -- In my day, we used to edit the inodes by hand. With magnets.
