C++::London talk: A polymorphic value-type for C++

On 25th January at CodeNode, London, Jonathan Coe presented polymorphic_value<T> to the C++::London meetup group.

The class template polymorphic_value is proposed for addition to the C++ Standard Library. The class template, polymorphic_value, confers value-like semantics on a free-store allocated object. A polymorphic_value<T> may hold an object of a class publicly derived from T, and copying the polymorphic_value will copy the object of the derived type.

About the presenter:

Jonathan is a mathematical developer using modern C++ and Python. He has worked in academia and the financial and energy industries. He's been a participant in the C++ standards committee since 2014.

C++17 Features—Bartlomiej Filipek

An extensive list of the future standard changes:

C++17 Features

by Bartlomiej Filipek

From the article:

In my last C++ summary (for 2016) I wrote that the draft for C++17 is the most important thing that happened. I’ve put a list of features of the new standard, and today I’d like to expand the topic so we can learn some more details.

C++ Status at the end of 2016—Bartlomiej Filipek

The view from Nov 2016 C++ Standard Meeting Issaquah

Hi all, I have been on airplanes for the last 10 weeks in a row, starting with CPPCON 2016 on September 16 2016. But first, I wanted to update everyone on the latest status of the C++ Standard meeting from Issaquah on Nov 7, 2016. Here is a blog post where you can see a video of what is coming for C++17 and download the slides. You can also see what happened in Issaquah for Evolution, Parallelism, Concurrency, and the latest status of the National Body Comments:
