Why are some C++ standard library design issues so difficult to fix once standardized?
Nicolai Josuttis and Jesper Pedersen discuss the design of Filter View in C++20, C++23, and C++26, and how Ranges design decisions can affect const-correctness, usability, and safety. #CPlusPlus #CPP #Cpp23 #Cpp26 #ModernCpp

I am pretty sure you all already know, but it's actually possible to have `requires` clauses at the end of a function declaration. Just like any other attribute.
This makes usage of ad-hoc requirements much more readable and greatly reduces the pressure to introduce custom concepts.
Why are so many teaching the front syntax instead of the tail syntax?

You don't realize just how good C++23 is until you take some old C++ code, paste it into #Godbolt, set the compiler flags to C++23, add a few concept-checking asserts, read the beautifully clear error messages from concepts, and fix your problem.

I wrote a blog post again:
𝗢𝘄𝗻𝗶𝗻𝗴 𝗮𝗻𝗱 𝗻𝗼𝗻-𝗼𝘄𝗻𝗶𝗻𝗴 𝗖++ 𝗥𝗮𝗻𝗴𝗲𝘀
The first article in a series discussing some of the underlying properties of C++ ranges, and in particular range adaptors.

Why do C++ templates confuse so many developers?
Because the syntax is tricky, the errors are cryptic, and most tutorials don’t explain the why behind the how.
In my self-paced course, we fix that. Step by step, you’ll see how templates work, so you can write efficient, reusable code with confidence. Join now and start mastering!And yes, you’ll also get a complimentary copy of my "Tips and Tricks with Templates" book when you book before April 30th.

[TUTORIAL] Learn Modern C++
"...una guida originale e autonoma per l'apprendimento dei fondamenti di Modern C++, destinata a costituire la base di un corso di autoapprendimento. Alcuni capitoli dipendono dal materiale presentato in quelli precedenti, per cui se ne raccomanda lo studio lineare. Ci sono anche post regolari che trattano argomenti o aree del C++ non presenti nel corso."

Remember the days when #Clang was the new kid on the block, pushing forward the smug old folks by implementing the newest and hottest stuff from #isocpp?
Not so anymore: These days it always seems Clang for which I have to provide terrible fallback hacks, when trying to explore the hottest and nicest of #moderncpp, where #GNU and #MSVC just deliver.

Great books!
I would recommend them and these two authors in general (Nicolai M. Josuttis and Bartlomiej Filipek) for everyone willing to structure their knowledge in (not so) modern C++ world.

I won't be the first to say this, but we need to retire the phrase "Modern C++". I mean, C++11 was 12 years ago.
I understand that branding was necessary back then due to significant changes in the language and library, but it is ridiculous to continue to cleave language versions like that.
For my part, I just removed "Modern" from a course title, and I'm not looking back. 🚀

Ever wanted to #switch on a #QMetaType, or just a random, non-literal constexpr char pointer, aka. #string? Search no more:

Don't judge me too much....refactoring some code ATM, and I tend to use a lot of ranges,
Problem is this code has lots of pointers, so getting access to the values is a pain.
So I made this https://godbolt.org/z/sx8K5qG8j to adapt pointer based inputs as needed.
Any refinement / blindingly obvious alternative to keep the range based code clean? -

So I finally have an example that underlines my gut feeling of the else-if-statements being #harmful in modern C++.
Consider test(char) being a function returning a std::optional<>:
if (const auto x = test('A'))
handle_a(*x);
else if (test('B'))
handle_b(*x);The function handle_b() will receive the invalid optional returned by test('A') instead of the one returned by test('B') without the compiler providing any warning.
Maybe something for your blog, @lefticus
