Anyway, std::nested_exception looks pretty trivial to implement given the bits that already exist in Boost.Exception. Would you be open to a patch providing an implementation?
What's wrong with struct whatever { }; struct translated: boost::exception, std::exception { }; typedef boost::error_info<struct tag_nested_exception,boost::exception_ptr> nested_exception; .... catch( whatever & e ) { throw translated() << nested_exception(boost::copy_exception(e)); } Elsewhere, instead of N2559 rethrow_nested: catch( boost::exception & e ) //or catch(translated & e) { if( boost::shared_ptr<boost::exception_ptr const> n=boost::get_error_info<nested_exception>(e) ) rethrow_exception(*n); } Emil Dotchevski Reverge Studios, Inc. http://www.revergestudios.com/reblog/index.php?n=ReCode
