Recently, my PR about support for Messenger HandleTrait return types was merged. I would like to use that work done to ability for QueryBus classes to "learn them" how to determine their results correctly, wherever they are called.

There's related PR to this missing functionality, which demonstrate what I want to achieve. The most reasonably (and the easiest way of doing it) from my understanding would be getting query-result mapping (which HandleTrait::handle method is aware now), and reusing it as the same input-output values for QueryBus::dispatch method (from the PR's example). Perhaps, using some annotations?

Maybe it is trivial to complete, but at the moment I do not know how to connect these dots 😅
I will try to push this topic forward, but any thoughts/ideas are welcome :)
