Quick A: yes
Recently on SO:
Is 'auto const' and 'const auto' the same?
The const qualifier applies to the type to the immediate left unless there is nothing to the left then it applies to the type to the immediate right. So yup it's the same.

Episode 125 of C++ Weekly.
The Optimal Way To Return From A Function
by Jason Turner
About the show:
In this episode of C++ Weekly Jason investigates the possible methods that one of two string values might be returned from a function. Which option is best? Which option can the compiler optimize the most? Do we take one return path or multiple return paths? Should a ternary be used?

Call for a more diverse program at Meeting C++ 2018!
by Jens Weller
From the article:
Last years track for new speakers was a great success, so Meeting C++ will dedicate a track to this now in every year. So I'd like to reach out to the C++ Community, who do you think has something interesting to say about C++ and could start speaking at this years Meeting C++?

Using C++17 std::optional
by Bartlomiej Filipek
From the article:
Let’s take a pair of two types <YourType, bool> - what can you do with such composition?
In this article, I’ll describe std:optional - a new helper type added in C++17. It’s a wrapper for your type and a flag that indicates if the value is initialized or not. Let’s see where it can be useful and how you can use it.

Passing Booleans to an Interface in an Expressive Way
by Jonathan Boccara
From the article:
In order to allow a function to behave in several different way, and to allow its caller to choose amongst these behaviours, we have several tools at our disposal. Plenty, actually.
There are various sorts of polymorphisms embedded in the language such as virtual functions and templates. And we’ve also seen that a caller can specify the desired behaviour explicitly at call site. We’ve seen how to accomplish this by using tag dispatching, and also how to choose between enums and tag dispatching depending on your need.
I now want to top it off with a really simple technique, that will cost you almost nothing, but one that will make your code much more expressive. And even if it’s not rocket science I’m sharing this with you today because I’ve seen many a piece of code that could have benefited from it...
