The Data::Iterator::Hierarchical module. What it is why I wrote it and bit about my experiences getting it ready for CPAN.

Data::Iterator::Hierarchical allows nested loops to iterate in the natural way over a sorted rowset as would typically be returned from an SQL database query that is the result of naturally left joining several tables.
