Information on how MooseX::Storage handles object references is notably absent. My approach would be to serialize and then deserialize a structure and then check whether you got one or two references what originally was just one reference to a common object.

Maybe you want KiokuDB, also by at least one author of MooseX::Storage.

This is what I did, and got two different references (addresses). I am not sure if I am misusing MooseX::Storage or if its simply not supported by it.

We already discussed this on IRC, but I will put it here so that others can see.

MooseX::Storage does not handle recreating references in this way. It is simply a serialization module that takes an object, decomposes it and writes it out to disk in the chosen format. This works best with object trees, meaning objects that do not share references with other instances, kind of a DAG (directed acyclic graph) but not exactly.

What you have going on here is more of an object graph, which is more appropriate for KiokuDB, which does handle shared object references in the way you need them.
