[boost] function_traits and functors

Is it possible to use function_traits to decompose functors?
Specifically is this supposed to work?

void test_helper( int a )
{
}

template< class Handler >
void test( Handler h )
{
   typedef typename boost::function_traits<Handler>::arg1_type ArgType;
}

int main()
{
   test( boost::bind(&test_helper,_1) );
}

Thanks,
