Talk: Lazy QObject tree traversal

This talk is about using modern C++ for improving iterating over QObject tree. I'm going to talk about some issues with the current non-lazy implementation and ways of fixing them.

During the talk, I'll show how to create a custom composable range object and use coroutines to implement getting QObject's children upon request. I'm planning to briefly describe Qt framework itself, ranges, and coroutines as well.
