i modified transform() subroutine acording to your recommendation — i moved from dereferecing $list hashref to using it as a reference. The speed near doubled :)

New benchmark results: 

             Rate  find_path find_path2  transform
find_path  6.52/s         --       -72%       -96%
find_path2 23.7/s       263%         --       -87%
transform   183/s      2702%       673%         --
