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, falling back to a traditional frontal
presentation style where applicable.

Didactic High Speed
-------------------

Smart Pointers
..............

:doc:`/trainings/material/soup/cxx/cxx11/move/index` is a complex topic to
explain. A smart pointer overview is a good thing to have anyway. Lets
start with that, and - through ``std::unique_ptr`` - get insight in what
*moving* is from a user's point of view.

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

Rule Of Five (Three, Zero), And Move Semantics
..............................................

Another good thing to have is a rule to fight against C++'s
shortcomings. This expains how to write *copyable* and *movable*
types, likewise.

* :doc:`/trainings/material/soup/cxx/cxx11/rule-of-5/topic`
* :doc:`/trainings/material/soup/cxx/cxx11/move/index`
* :doc:`/trainings/material/soup/cxx/cxx11/perfect-forwarding/topic`, only
  to show that this is a different concept but looks syntactically
  much like *moving*.

Multithreading, Memory Model
----------------------------

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

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

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