Pull request description:
This PR:
- is a pure refactoring with no behavior change
- gets rid of `QMetaObject::invokeMethod()` "dynamic" calls, i.e., without compile-time checks of a called function name and its parameters
- replaces `std::bind`s with lambdas, making parameter permutation (including parameter omitting) explicit
- makes code simpler, more concise, and easier to reason about
Additionally, debug messages have been unified.
