  // The ASSERT_MESSAGE function is a small helper function to assist in printing an informative
  // message in case an assert fires. This function builds on the ideas of Matthew Wilson, who
  // directly combines a C-string error message with the run time expression (Imperfect C++,
  // ISBN: 0321228774):
  
     \code
     assert( ... &&  "Error message" );
     assert( ... || !"Error message" );

  // However, both approaches fail to compile without warning on certain compilers. Therefore
  // this inline function is used instead of the direct approaches, which circumvents all compiler
  // warnings:
  
     \code
     assert( ... || ASSERT_MESSAGE( "Error message" ) );
