My AMA yesterday is up on YouTube

Boy, Jens Weller turns these things around quickly! Thanks again, Jens, for having me on your Meeting C++ Live show.

I’ve put a list of the questions, with timestamped links, below…

All the questions and answers, with links

00:19 What are you up to with C++ currently / what keeps you excited?

04:04 Sean Baxter has finally written up a proposal to bring borrow checking to C++, to improve safety. What are your views on his proposal and what approach is Cpp2 planning?

08:48 Is there a long-term vision for C++? How can C++ maintain its relevance in the next 20 years?

13:14 What is your favorite C++ editor/IDE when not using Microsoft Visual Studio?

14:19 Will networking be in C++26?

17:43 Why is MSVC 2022 falling behind Clang and GCC on C++23 and C++26 features?

21:21 What is the roadmap for Cpp2? Whether it will be fit for production use?

26:30 Should the stdlib be split in two parts. One with slow changes and one with fast changes. E.g., ranges were introduced in C++20 but finished in C++23. I am still missing some features.

29:34 Are there plans to address ABIs with interfaces or other features in C++?

36:18 What is your answer to the growing complexity of C++ to be learned especially by novices? How would we teach C++ (e.g., at the university) if it gets larger and larger?

40:53 In the context of C++’s zero-cost abstractions philosophy, how do you see future proposals for making bounds checking in std::vector both safer and more efficient?

47:13 Are C++ safety initiatives arriving too late to fend off the growing adoption of Rust for “safe” low-level development?

55:25 What is the status of the profiles proposal in C++? Will some of it be part of C++26 or C++29?

57:35 The Common Package Specification, which looked very promising, seems stalled. Why is tooling in the language not a priority?

59:11 What do you think of std::execution / P2300R10? The API changed a lot across papers, and to me is quite a piece of work for library implementers to integrate.

1:04:35 Aren’t you afraid that reflection might be misused too much (e.g., use it for serialization)?

1:06:46 If local uninitialized variables are no longer UB, how will they behave? Could you please elaborate a bit on that?

1:11:30 How is the Contracts TS coming along? What are your thoughts on Contract Based Programming, in general?

1:15:56 Any chance of having type erasure (mainly std::any) in MSVC reimplemented not on top of RTTI? Unfortunately the current implementation makes it unusable in places where symbol names are left behind by RTTI.

1:17:38 What happened with the official publication of the C++23 standard?

1:22:31 Preview of my keynote next month at Meeting C++.
