C++20

Monads in C++? What a strange name for a post. But it's not so strange. With std::optional C++17 gets a monad. The ranges library from Eric Niebler and the extended futures are also monads. For both, we can hope for in C++20.

We stay in the year 2020. With high probability, we will get concepts. Of course, waterproof statements about the future are difficult but the statement is from Bjarne Stroustrup (Meeting C++ 2016 at Berlin).

A small-time jump and we are in the year 2020. C++ will get - as far as the future is predictable - the new ranges library. Thanks to Eric Nieblers library, working with the Standard Template Library (STL) will become much more comfortable and powerful.

Which functional feature can we expect with C++17, for which functional feature can we hope for with C++20? This is exactly the question I will concisely answer in this post.
