New description:

 The current implementation of boost::result_of doesn't permit Fn in
 boost::result_of<Fn(Args...)> to be a reference to a class type.
 I would like to see that changed. Allowing reference-qualified function
 object types would be in useful with c++11's explicit reference
 qualification of member functions (n3090 / 13.3.1/4), and this change
 would bring boost::result_of more in line with c++11's std::result_of,
 which does allow "reference[s] to function object type[s]" (n3090 /
 20.7.6.6)
