This is not possible, because:

 1. Boost.Function object might not correspond to a function at all,
    but to a function object passed though boost::bind.
 2. Even if it corresponds to a function, getting the name is only
    possible using debug information, and it might not be available,
    and there's no portable lib to access debug information
