  21 //  Exceptions were originally thrown via boost::throw_exception().
  22 //  As throw_exception() became more complex, it caused user error reporting
  23 //  to be harder to interpret, since the exception reported became much more complex.
  24 //  The immediate fix was to throw directly, wrapped in a macro to make any later change
  25 //  easier.
