 There is hope. Just specialize boost::phoenix::result_of_xxx
 (e.g. boost::phoenix::result_of_plus).
I specilized result_of_multiplies and still no luck:
#include
#include<iostream>
#include<typeinfo>
#include
namespace boost{
namespace phoenix{
using namespace boost::units;
template<>  //in general template
struct result_of_multipliessi::length, quantitysi::length
...
...
{
  typedef quantitysi::area  type;
};
}}
The type-deduction respects references. Phoenix2 passes in references.
The code should be:

     template<> //in general template
     struct result_of_multipliessi::length&, quantitysi::length&>
     {
         typedef quantitysi::area type;
     };
