And if you decide to try these builds, please, inform us of any issues you run into or any inconveniences you experience as early as possible, so we have time to investigate and can try to address them before the release...

Decorating with a side effect -- Krzysztof Ostrowski
A taste of functional stack of effects.
Decorating with a side effect
by Krzysztof Ostrowski
From the article:
Logging is one of such overused features, that leads to costly side effects (consider distributed logging, a DLT, prevalent in automotive industry). This article describes a technique that is used to extract side effects brought by logging, and then compose with them back in a well defined manner.

C++20 Reference Card
by Bartlomiej Filipek
From the article:
While the C++20 Standard is still being finalised and polished, we know all of its core features. At first, the new specification of the language might sound complex and overwhelming. That’s why, if you want to have an overview of the core elements and get the bigger picture, you can have a look at my new reference card...

C++ Modules conformance improvements with MSVC in Visual Studio 2019 16.5
by Cameron DaCamara

C++20 is right around the corner. Along with the new standard comes the much anticipated Modules feature! The compiler team initially announced that we were working on the Modules TS back in 2017 and since then we have been hard at work improving the feature and improving compiler conformance around this feature. We finally feel it is time to share some of the progress we have made on the conformance front for Modules...

How to Short-Circuit a Sequence of Operations with a Boolean Value--Jonathan Boccara
Boolean and bit operators are not the same.
How to Short-Circuit a Sequence of Operations with a Boolean Value
by Jonathan Boccara
From the article:
Interrupting a sequence of operations when one of them fails is a common problem in computer programming. There are plenty of elaborate ways to code that, ranging from exceptions to monads to static exceptions.
One of the techniques to stop such a sequence of operations that is not so sophisticated, but that can be found in existing code, is to use a boolean. This relies on each step producing a boolean flag to indicate if it succeeded or failed, and to stop executing steps at the first failure.
However, simple as it is, this technique can lead to code that doesn’t do with it looks like...
