[boost] boost::result_of

I can't seem to get the result_of template to function, I've tried:

#include <boost/utility/result_of.hpp>

typedef boost::result_of<F>::type t;

with F=

int (double)
int (*)(double)
int (&)(double)
std::unary_function<double,int>

and all give a long list of errors.

I believe that all of these should be OK?  So am I doing something obvious 
wrong (I'm using VC7.1 BTW in case that makes a difference)?

Thanks,

John.
