How about boost::exception<> ? I don't know if that already conflicts
with anything already being used in boost, and makes it different from
std::exception -- but in which case, it would be good to have all
boost::exception<> instances drive from std::exception as well, so as
to make it catchable in standard exception handling code. Does that
make sense?

exception_string sounds alright. or perhaps something like a general
"info" could work:

throw boost::exception<foo>() << boost::info_string<tag>("value");
...
throw boost::exception<foo>() << boost::info_errno<tag>(1);
