Ichthyostega 23b4a54e79 Metaprogramming: detect structured types
This solution checks only the minimal precondition,
which is that a type supports `std::tuple_size<T>`.

A more complete implementation turns out to be surprisingly complex,
since a direct check likely requires compile-time reflection capabilities
at the level of at least C++23
 - `std::tuple_element<i,T>` typically implements limits checks,
   which interfere with the detection of empty structured types
 - the situation regarding `std::get<i>()` is even more complicated,
   since we might have to probe for ADL-based solutions, or member templates

The check for minimal necessary precondition however allows us to
single out std::tuple, std::array and our own structured types in
compilation branching, which suffices to fulfils actual needs.
