C++17 makes a new step.

Trip Report: C++ Standards Meeting in Issaquah, November 2016

by Botond Ballo

From the article:

Last week I attended a meeting of the ISO C++ Standards Committee (also known as WG21) in Issaquah, Washington (near Seattle). This was the third and final committee meeting in 2016; you can find my reports on previous meetings here (February 2016, Jacksonville) and here (June 2016, Oulu), and earlier ones linked from those. These reports, particularly the Oulu one, provide useful context for this post...

Why you should use Boost.MultiIndex (Part II)

by David Gross

From the article:

A few weeks ago, I posted the first part of this article, where I explained the advantages of Boost.MultiIndex over the standard containers when you need to have multiple views on a set of data.

In this second part, I would like to talk about the benefits you can get from using Boost.MultiIndex as a single-index hash table, as a replacement of std::unordered_map.

One interesting and powerful aspect of Boost.MultiIndex is that it allows you to add an index of type T, where T is different from the stored type. And it is more frequent and useful that you could think.

Compose and curry as folds

by Nick Athanasiou

From the article:

In a previous post we introduced C++17 fold expressions and described a way to extend them for arbitrary callables. Implementation details don’t matter for what we’re elaborating on here but it should be clear that (given the tools we developed) the following is possible:

(Op<F>(args) + ...)
(... + Op<F>(args))

Guaranteed Copy Elision -- Jonas Devlieghere

Guaranteed Copy Elision deserves some attention!

Guaranteed Copy Elision

by Jonas Devlieghere

From the article:

The new C++17 standard brings many exciting new features. A smaller, more subtle improvement it brings is guaranteed copy elision. The keyword is guaranteed, as copy elision itself has always been part of the standard. Although it might not be a change as radical as, say, structured bindings, I'm very happy to see it made it into the standard.
