thank you er and Mathias for your answers,

Does Boost have a generalization of std::plus and std::multiplies (std_function.hpp)?

How about the boost::lambda arithmetic operators, possibly in   combination with ll_static_cast<Tp>, and -if necessary- put the   result in the functor wrapper boost::function

?

what is "ll_static_cast<Tp>"? after that part I got lost.

I had such a class in our libraries, but threw it out and replaced it   with lambda expressions

but I need this generalization of multiplies as one of the default parameter of a template, how would you pass a lambda expression as template parameter? The reason I returned to my post is that today I found boost/mpl/ plus.hpp and boost/mpl/multiplies.hpp which seem to answer the first part of my question (although not the syntactic sugar part). Thank you, Alfredo
