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

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,
