What if I wanted to do something like:

int main()
{
   using namespace boost;
   using namespace lambda;
   typedef function< double() > F0arg;
   const double x1=1.1, x2=2.2;
   F0arg f = bind( ret<double>(_1*_2)(x1,x2) );
}

Or, slightly more generally, if we want to bind other boost::function  
objects and not POD:

   typedef function< double(T) > Func;
   Func func1, func2;
   ...
   F0arg f = bind( ret<double>(_1*_2)(func1,func2) );

Any ideas here?
