This changeset is a sketch how to switch the entire implementation of the ''Invocation Adatper'' over to a generic argument usage scheme. This requires the ability to - detect if some argument is actually a ''structured type'' - investigate components of such a structured type to draw a distinction between »Buffer« and »Parameter« - ''lift'' the implementation of simple values to work on tuples - provide a way to ''bridge'' from ''tuple-style'' programming to ''array access'' As a building block, we use a new iteration-over-index construct, based on an idea discussed in https://stackoverflow.com/q/53522781/444796 The trick is to pass a `std::integer_constant` to a λ-generic
