abigail-ii I think you are talking about Flat File Fun (or You Just Saved My Class) above. I did read the node, and I gave a link to Data::Dumper for one of the possible ways to store his data. Unlike you I assume the OP was not really asking what module he should use and take the first one that was posted but maybe a list of modules that could be used. I read (and still do) his question as a fact finding question to see what modules others would use to serialize his data.

Your responce says This is not an easy question to answer. No doubt, you'll see quick posts saying "use Date::Dumper", "use YAML" or some other serialization technique. But then what. So you decide the pick YAML, what's next? That's the wrong time to start asking questions. First you have to know, what is that data I need to save? Why am I saving? Is it for persistence, ... You assume the OP is going to jump on in and use Data::Dumper to serialize based on my post, then after long hours of work have a light turn on and question how he is doing it. -- I assume he is going to read the docs and see if it fits his needs (esp since he does not fully describe his structure), hell he may even have a brain and consider looking at all the options posted and chose one that fits his needs or modify the way his data is formed to make it easier to scope out the dump to disk. Just because you read a question one way does not mean the other guy answering questions or tossing info out there does not read the question.
