It works like this:

struct S {
    int f(int);
}
typedef int (S::*f_type)(int);
typedef boost::result_of<f_type(S*, int)>::type f_result_type;

Note that this is not very useful if you want to deduce the return
type of the function named f in some arbitrary class, because you
need to know the type of the member function pointer to
use result_of.
