It appears that std::string* is not serializable. I have need to serialize them, and I'm considering adding the old, unused code in boost/serialization/string.hpp (the stuff #if 0-ed out and marked with "left over from a previous incarnation - strings are now always primitive types") to serialize std::string*'s. I have 2 questions before doing so. 1) What is the rationale for making std::string a primitive, track_never type? After an extensive rereading of the docs, I'm left with only a hazy understanding of what the implications are for primitive vs. non-primitive status. 2) Can Robert (or anyone else) give me a sense for how likely I am to get myself into trouble doing this? If it matters, I don't need to be able to read old archives containing std::string's. Thanks, Zach Laine
