I'm using uncaught_exception_count in a few places of Boost.Log to implement 
guards that do the main work in destructor and only when an exception is not 
being thrown. For instance, this expression:

  BOOST_LOG(lg) << foo();

will create a guard object that will collect the result of foo into a stream 
and emit a log record on destructor if foo doesn't throw.
