[Early Access] Advanced Kotlin

About the Book

You can be a developer without knowing those topics, even a good one, but at some point, is will start blocking you. You likely use on daily basis tools made using features described in this book - libraries based on annotation processing or compiler plugins, classes using variance modifiers, functions with contracts, and property delegates. But do you understand those features? Would you be able to implement similar tools yourself? Would you be able to analyze and debug them? This book is about to change it. It concentrates explicitly on the most advanced Kotlin topics, which are often not well understood even by senior Kotlin developers. It should equip you with the knowledge and show you possibilities you haven't seen before. I hope you enjoy it as much as I enjoyed writing it.
