          at least one of the two args is not of type "c"
          when c: c value is embeded in bind_first or bind_second
                  and the operation reduces to an unary one
          when a: if it is a field_convertible, it should be wrapped

          when c: no wrapper is need
        implementation:
          The a and n cases are grouped, thanks to the wrapper_traits
          and it remains to cases :
            1) both args are  field_expr_v2_nonlinear or a function 
            2) one  arg  is a field_expr_v2_nonlinear or a function and the second argument is a constant

    The day finally came. The Deadlock Empire opened its gates and from them surged massive amounts of soldiers, loyal servants of the evil Parallel Wizard. The Wizard has many strengths - his armies are fast, and he can do a lot of stuff that we can't. But now he set out to conquer the world, and we cannot have that.

    You are our best Scheduler, commander! We have fewer troops and simpler ones, so we will need your help. Already two armies of the Deadlock Empire are approaching our border keeps. They are poorly equipped and poorly trained, however. You might be able to desync them and break their morale.
