Note: on #ConfederateHistoryMonth: just a friendly reminder that confederates committed treason to stupidly attack a country with 3 times their manpower and ALL of the military industry, primarily to defend the right to own, trade, beat and rape other humans.

@david_sankel If `s` is address-escaped / a global, a conforming compiler may not introduce a write to `s` when `b` is `false` without potentially introducing a data race.

Given 'bool b', 'unsigned x', and 'unsigned &s'. Is there a difference between 'if (b) s+= x' and 's += b*x'? Honest question.

@Angles305 @Chinchillazllla Why are crickets so strongly attracted to bad jokes?

@Chinchillazllla Thank you for the bug facts. If you have a moment, I have firefly questions. 1. Have they suffered a population hit in the last few years? I never see them anymore. 2. Does anyone sell fireflies like they do for crickets? 3. Unrelated—ever prank someone with a bunch of crickets?

@falco_girgis @vzverovich "Supporting" is a bit of an overstatement: support for deducing this in MSVC is partial. (I don't recall precisely why other than "it doesn't work in modules yet" but @starfreakclone could explain in detail if you like.)

@vzverovich Now they're supporting deducing this first, it looks like? They fixed their C preprocessor!? WTF is happening over there?!!?

Current status: defending Microsoft and MSVC on Reddit.

@vzverovich @basit_ayantunde @mattgodbolt Using "unstabilized" features with libc++ on Compiler Explorer is, err, expert-friendly: godbolt.org/z/aEffYbhcc

@CoderCasey @basit_ayantunde @mattgodbolt Then libstdc++ is further than I thought =)

3 years after C++20 and only MSVC really allows you to use std::format

@vzverovich @basit_ayantunde @mattgodbolt (github.com/compiler-explo…, for those lacking context.)

@vzverovich @basit_ayantunde Your Compiler Explorer example is using libstdc++. See @mattgodbolt ? This is why.

@ciura_victor @JamesMcNellis @seanbax @visualc Ah yes, the "Invisible C++" years.

@JamesMcNellis @seanbax @visualc Yes, there were previous versions of C and C++ compilers and tools released by Microsoft before “Visual C++”.

The first version of Visual C++ was released 30 years ago today 🎂 (Feb 23, 1993) #cpp #cplusplus @visualc

Once is an anomaly. Twice is a coincidence. Three times is a pattern. Four times is enough. We've had enough of harassment and coverups. We have failed to make the C++ community safe. It's time for change. Leadership must prioritize safety.

@rodgertq @nichols_senator Hopefully they'll ban dihydrogen monoxide next. It's been found in the water supply of every major urban center in America!

Today I introduced a bill to ban all messenger ribonucleic acid technology (mRNA) in the State of Idaho, and we passed the Freedom in Education Savings Account out of the Senate Education Committee to fund students and not systems, putting families in control over their ed $.

@TheAyenem @hankadusikova @vzverovich That's the conversion operator version of a deduced return type. The compiler deduces what type the conversion operator produces by looking at the return statements in the function body.

@hankadusikova @vzverovich @CoderCasey What does the `auto` do in `operator auto()`? Is that like a conversion operator to any T?

Printing hello world in C++ has never been easier.

@hankadusikova @vzverovich

@vzverovich It's less readable _and_ less efficient!

@vzverovich Why bother with `hello[]` when you could simply (std::cout << ... << str)? (godbolt.org/z/efG97nMjP)

@elchefe "Your belt can be a tool to save your life in a Self Defense situation - but certainly not this one."

If this ain’t some McDojo bullshit like…

@ciura_victor @MatRopert "C with member functions"

@MatRopert 🤣 `class` was a mistake in C++. Both for structures and templates. Just unnecessary. Peer pressure, cargo-cult, whatever you want to call it, it shouldn’t have been there. But “C with classes” sounded so much better than “Better C” 😄 #cpp #cplusplus

What is the dumbest C++ compile error and why is it "type name first seen using 'class' now seen using 'struct'" ?

@LAK132 If that's the case, it's probably not a regression which means we won't be able to do much about it unless very many customers report it. Sorry!

@LAK132 Default constructing a vector<T> doesn't instantiate any of T's special member functions, except the destructor: godbolt.org/z/PaWEYMnb9. What problem are you seeing?

@vzverovich Undefined Behaviormobile

@ericniebler Where's the "Request Changes" button in the Twitter code review UI?

Hey, there's *nothing* wrong with the C declarator syntax, OK?
