40//
41// Exceptions were originally thrown via boost::throw_exception().
42// As throw_exception() became more complex, it caused user error reporting
43// to be harder to interpret, since the exception reported became much more complex.
44// The immediate fix was to throw directly, wrapped in a macro to make any later change
45// easier.
