Agenda: C++ - Overview Of New Language Features (Around C++20)
==============================================================

The audience consists of professional programmers who are not new to
C++. As such, rather than reinforcing each topic through exercises, it
is more important to *discuss* matters and to develop a common
knowledge and a common sense.

Throughout the training, the presentation style will be
live-coding-by-trainer, only falling back to a traditional frontal
presentation style where applicable.

News From The Library
---------------------

* Container and algorithms overview (:doc:`here
  </trainings/material/soup/cxx03/060-stl/index>`). Show hash-table
  based data structures ``std::unordered_set<>`` and
  ``std::unordered_map<>`` [#make_material]_.
* ``std::array<>`` [#make_material]_
* Execution policies of parallel algorithms [#make_material]_
* ``std::span<>`` [#make_material]_
* Ranges and views (:doc:`here
  </trainings/material/soup/cxx11/ranges/index>`)
* ``std::fmt`` (vs ``printf()``) [#make_material]_
* :doc:`/trainings/material/soup/cxx11/filesystem/topic`. In addition
  to basic functionality, show how to handle UTF-8 encoded paths
  (``std::filesystem::u8path``) [#make_material]_
* From :doc:`/trainings/material/soup/cxx11/any-variant-optional/index`

  * :doc:`/trainings/material/soup/cxx11/any-variant-optional/any`
  * :doc:`/trainings/material/soup/cxx11/any-variant-optional/variant`

* ``std::tuple<>`` [#make_material]_

Multithreading, Memory Model, Smart Pointers, And Move Semantics
----------------------------------------------------------------

This section is a bit involved as all of this is somehow related.

* From :doc:`/trainings/material/soup/cxx11/multithreading/index`

  * :doc:`/trainings/material/soup/cxx11/multithreading/memory-model/topic`. This
    briefly shows what a race condition is, and gives mutex examples.

* From :doc:`/trainings/material/soup/cxx11/smart-pointers/index`

  * :doc:`/trainings/material/soup/cxx11/smart-pointers/introduction`
  * :doc:`/trainings/material/soup/cxx11/smart-pointers/uniqueptr`
  * :doc:`/trainings/material/soup/cxx11/smart-pointers/sharedptr`
  * :doc:`/trainings/material/soup/cxx11/smart-pointers/weakptr`
  * :doc:`/trainings/material/soup/cxx11/smart-pointers/040-closing-words/topic`

* :doc:`/trainings/material/soup/cxx11/move/index`. Explain
  :doc:`/trainings/material/soup/cxx11/perfect-forwarding/topic`, 
  only to show that this is a different concept but looks syntactically the same.
* :doc:`/trainings/material/soup/cxx11/multithreading/atomic-shared-ptr/topic`. 

C++ Executed At Compile Time (The ``constexpr`` Engine)
