..Back to C++, kinda, yeah .. though for the inner_product (and this is
where variadic template parameters would be a nice fit):

  fusion::inner_product<SequenceA, SequenceB, ...> { /*...*/ }

(, or whatever the syntax was - forgot the exact semantics Doug Gregor
implemented)

and your dot_product would be as specified.
