This might just be the most wild compiler bug I've encountered: github.com/llvm/llvm-proj…

Is there a reason that `std::vector<int>() == std::deque<int>()` should not compile in C++?
My least favorite part of twitter is all the "threadreaderapp please unroll" spam.
Me: "Are you almost done with this?" Them: "Don't worry, I have hardly everything left to do."
David Stone retweeted
While porting my code to use modules, I find myself wanting the opposite of include-what-you-use.org. In other words, dont-import-what-you-dont-use. Anyone working on that? :)
Is it legal for the rhs of the copy assignment operator of vector to be in the data of the lhs? godbolt.org/z/7fTcbvbqb Asking for a lightning talk =D
Given ```cpp struct empty{}; union u { empty e; char c; }; unsigned char f() { auto const storage = u(empty()); return reinterpret_cast<unsigned char const *>(&storage)[0]; } ``` What does `f` return?
Why does clang generate different code for the volatile case? godbolt.org/z/s5ccxxY47 Or maybe a better question is: why don't both compilers generate that code for both cases?
When people say "Nuke it from orbit, it's the only way to be sure", I wonder if they've ever seen a movie or read a book. "Are you sure we got it?" "Yeah, there's no way anything could have survived that." What happens next in this story?

I think when lowering the initializer_list I need to evaluate the elements directly into it, rather than into an array intermediate. Start with init_list.cur and end pointing to the array. Initialize element 0, increment end, initialize 1, increment end, etc. Yes...

@Lowes I expect the picture of blinds on your website to be actual blinds, but it's clearly AI generated. The blinds on the far right don't make any sense, the bottom right corner can't decide if it's an armchair facing left or right or a table made of glass or plastic...
you think duck typing is bad? wait until you see their handwriting
Bro I’m just trying to order a sandwich from Wendy’s what the heck is this 😭
@the_aiju imagine rejecting a bonus. “this is just a constant lump sum, I can just work more!!”
Feels good to have a C++ object model that dumps indirect binding. What were they smoking when they decided to allow this? It totally blows up type safety.
@david_m_stone - I just today saw your 2019 "constexpr function params" talk. I don't know if the feature is dead in the water or very near completion, but if you need arguments in the committee then I, for one, could definitely use it for a constraints-library I am writing.
We need a standard [[pure]] attribute, or a way to imply it with assume.
@hankadusikova @RavivDan @david_m_stone Me too, but LTO is good at warning on ODR violations... And I'm sure David isn't ignoring linker warnings... Right?
@visakanv might as well go all the way and use 24 hour time like most of the world does
@bayeslord This is unfair. In this article, I will demonstrate that 1. ACX posts are an optimal length, 2. In general, a marginal increase or decrease in the length of an ACX post leads to decreased comprehension, 3. According to polls, the majority of readers .... (1/282)
Let me introduce you: GPT-4.5
I really can't tell if this is computer generated or a clever parody of it
Definitely my favorite of all the reflection examples in P2996 (and not just because I wrote it): a zero-annotation command-line parser: brevzin.github.io/cpp_proposals/… Very excited to see this coming together!
