It 'could' be done using the preprocessor, but you would have to
encode the size at the call site since the preprocessor knows nothing
of the C type system.

If you can get the arguments type to be boost::array or fusion::vector
or so, then fusion::invoke would be perfect if you are needing to call
something with them.
