Hi, the threads, threads::share modules allow sharing of some simple data structures among threads (e.g, scalar, array or hash), I'm in a situation where I need to share a more complex structure, something like a hash or hash references, several levels deep. The problem is that I obtained this structure from another module (e.g., XML::Simple), so I cannot really declare all the data inside to be "shared". Of course, updating such a structure can also be a pain if I want to keep the "shared" part straight. I've come up with a solution which is to serialize the structure into a scalar (such as using Storable's freeze/thaw), which works, but I feel bad about it. Any other solutions, comments? Thanks.
