Hi Jody

This looks like a good plan. FWIW, I don't currently care whether the
boost::type_info is implemented in terms of std::type_info (and
therefore necessarily exposes the non-standardness of the underlying
platform) or a sophisticated technique to emulate standard behavior. My
uses of typeid are so limited that I can easily avoid the bugs of the
platforms I care for. In other words, I only need std::type_info with
comparison operators. Other proposed libraries seem to have similar
