It looks like a good framework, but I had some thoughts on how we could get more type safety and reusability from the code.

I think that this might be a bit clearer as a struct. That would allow us to do diProp.index instead of std::get<0>(diProp). Of course, we could still overload std::get if we really needed to.

Ah, for sure! I was using the std::tuple just to quickly spin up a working example, although all the std::get<> pollution quickly became rather tiresome. struct or class definitely the way to go.

@rprospero here is the stuff I came up with when looking into custom model interfaces. Still uses a template class sitting alongside the data (here focussing just on
std::vectorand tables) but the template derives from a concrete base class which the Qt model leverages to do all the work.Thoughts on how any of this (if any!) can work with your own approach welcome!
