I find myself repeating what I said earlier, but I think this is the essence of what you're trying to achieve with the "visitor" approach of hanling exceptions: you are replacing the "catch-by-type" semantics of C++ with "catch-everything-and-examine-its-value" semantics.
Actually, the way exceptions are handled is completely independent of boost::exception itself. One could use chain of catch, Jeremy Day's library or the approach suggested by Andreas Huber or any combination. The explicit support for a "exception transformer" inside boost::exception is not needed (visiting all stored data is a different thing). So my arguing is OT in this regard. /Pavel
