Another thing (from the same domain) that I found especially difficult to 
deal with in my logging implementation is "intermixed logging":

BOOST_LOG(..)  << "Print result of f(): " << f();

...
void f() {
   BOOST_LOG(..)  << "Enter f()";
...
   BOOST_LOG(..)  << "Exit f()";
}

Now to make it properly formatter isn't trivial at all.
