I just decided to give #MEV a try. I think I found a niche protocol where there is still no competition but payouts should be decent, even for a noob like me. I will post every now and then about my progress, I need some minimal human contact with fellow nerds. I'm starting to write my bot in #cpp tomorrow. But first I need to catch up on the new language developments. I last used #cpp11 and so much cool stuff has happened between then and #cpp23.

Experience first-hand the quality of KDAB's training courses and join the KDAB Training Day on November 27th in Berlin. Early-bird tickets are available until the end of July. #qtdev #qt6 #qml #cpp23 #cpp #rustlang

Join the "What's new in C++23?" training during the KDAB Training Day on 27th November to explore how the latest C++ standard helps to write modern, efficient, comprehensible, robust and future-proof code. #cpp #cplusplus #cpp23 #qtdev

A feature 38 years in the making:

The KDAB Training Day will be back in Berlin on Nov 27th this year, right before Qt World Summit (Nov 28th-29th) Ideal to take part in both events!

C++20 modules are now foolproofly usable in latest release of MSVC (v17.6.4).

Standard library is precompiled automatically.

CMake code is simpler, target_include_directories are no longer needed.

It only took 3 years. Yaaay!

LLVM and Clang 16 are out with more complete C++23 and C23 support.
https://releases.llvm.org/16.0.0/tools/clang/docs/ReleaseNotes.html

I wonder if "import std" is finally usable in a real-world codebase?

I am thinking about writing consteval Toml parser using #cpp23. Keys are tricky because there is a lot of concatenation involved.

I just an idea of buildimg a dictionary of words that comprise each key and assign each word a numerical index. I could then compute unique ID for each key.

The problem of compile time hashing of dynamic strings would reduce itself into maintaining a sparse vector of numbers - much better!

Technically this would no longer be a hash as it would be possible to compute the full string back from the ID.

Still, thats a ton of constexpr code to write!

Does anyone know why the paper N4937 in the mailing-2023-01 is not accessible ?

What does the phrase, "an initialization of auto always decays" mean ?

doesn't presence of 'auto' keyword imply a template which doesn't have implicit conversion. anyone knows ?

It's done! The next generation of the C++ programming language standard C++23 is final and has been approved to be send to ISO.

Here is a great talk at @meetingcpp 2022 conference by Timur Doumler (@timur_audio@twitter.com) about the new features of #Cpp23 #Cplusplus: https://www.youtube.com/watch?v=QyFVoYcaORg

@jfbastien Is your proposal P2723R1 (zero initialisation of automatic storage duration variables) one of the proposals that could be voted into C++23 this week?

I'm hoping so, but I'm not too sure where to look, and I'm worried this might be a very rapid turnaround time for WG21...

Few days ago I was ranting about lack of proper use-after-move detection with unique pointers in #cpp.

While not a perfect fix, #cpp23 has constexpr smart pointers so you can detect this particular error using compile time unit tests.

Trivia question:
Do you know how to write compile time tests?

From the last meeting of the ISO C++ commitee meeting in Kona. Excited for this change, this thing alone has bitten me in the ass many times in the last year.
