Then I guess in fusion you would do :

fusion::dot_product<SequenceA, SequenceB> : fusion::inner_product< SequenceA,SequenceB, boost:functional::multiplies,boost::functional::plus
{};
Just to clarify the terminology: that inner_product function is still essentially a dot product. A dot_product is anything that looks like product = x*x + y*y + z*z + ... where + and * can be any ring operations. A general inner product function would have to allow for cross terms, e.g., product = a*x*x + b*x*y + c*y*y + ... So, I'd go for calling everything dot_product and giving it default arguments for + and *. Geoffrey
