mpl::plus and mpl::multiplies are not function objects.  You can't use them with int, for example.  They are metafunctions that mainly work with MPL Integral Constant Wrappers:

I see, I got confused because in the source (which is very difficult to read with all the defines, there is a point where you "#define AUX778076_OP_TOKEN +" so I though that it really implemented a functor. But it seems that the "token" is used only for the compile- time constants in the code after all. Thank you, Alfredo
