that requires using the same bit of code again and again.

Whenever I see this phrase, deafening alarm bells and sirens go off in my head. In the vast majority of cases, any time you're using the same (or similar) chunk of code over and over again, you can probably do better with a subroutine. In the case of a sub for traversing a complex data structure, you may want to use a callback hook to provide the specific functionality.

There are modules available on CPAN to traverse complex data structures. One that I'm aware of is nothingmuch's Data::Visitor::Callback, but I'm sure there are more... Data::Traverse looks like it fits the bill, too.	[reply]
