Boost C++ Libraries

...one of the most highly regarded and expertly designed C++ library projects in the world. — Herb Sutter and Andrei Alexandrescu, C++ Coding Standards

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