+Internal implementation details of the `CompletableTask` hierarchy are greatly inspired [by the work](https://github.com/lukas-krecan/completion-stage) done by [Lukáš Křečan](https://github.com/lukas-krecan). A description of his library is available as a two-part article on DZone: [Part 1](https://dzone.com/articles/implementing-java-8) and [Part II](https://dzone.com/articles/implementing-java-8-0). It's a worth reading for those, who'd like to have better understanding of the `CompletableTask` internals.
