Thank you!

I was rearranging some code when I started to use Andrey's logging  
library. With empty() I can implement a function loading a shared library  
and calling types like this:

bool init(const std::string &name)
{
   shared_library lib(name);
   if (!lib.open())
     BOOST_LOG(mylogger) << "error ...";
   else if (!lib.call(types))
     BOOST_LOG(mylogger) << "error ...";
   else
     BOOST_LOG(mylogger) << "no error ...";

   return lib.is_open() && !types.empty();
}

As you see it was not a very important request. :)
