I just have one comment on... comments:

I aggree that comments on code are often be redundant, and so should be used with caution.

But comments on data should be all over the place, especially with Perl complex types (yes, I mean hashes!), a simple comment like

my %nodes; # node_id => ref_to_node

can go a _long_ way to help you or anybody else who has to maintain the code 3 month later.
