[boost] [Boost.Test] return value of macros

Hi Gennadiy,

I often want to output message or do additional test of another test fails.

It would be cool if I could do it like this:

if( !BOOST_CHECK_CLOSE( aStarEcr, close,  0.0001 ) )
{
      BOOST_MESSAGE( "\nA* sequence: " << aStarSeq );
      BOOST_MESSAGE( "\nClose sequence: " << closeSeq );
}

But, AFAICT, the macros are implemented this way:

#define BOOST_CHECK_WITH_ARGS_IMPL( P, check_descr, TL, CT, ARGS )  \
do {                                                                \
     BOOST_TEST_PASSPOINT();                                         \
     BOOST_TEST_TOOL_IMPL( check_frwd, P, check_descr, TL, CT )      \
     BOOST_PP_SEQ_FOR_EACH( BOOST_TEST_PASS_ARG_INFO, '_', ARGS ) ); \
} while( ::boost::test_tools::dummy_cond )                          \
/**/

Do you think it would be possible have a bool returning function
instead of the while loop?

best regards
