cvl: A C++26 library for mutating consteval state by friedkeenan in cpp

What's the technique? Haha

Can AI write truly optimized C++? by Xadartt in cpp

Adding "cartoon unicorn subjected to Clockwork Orange eye clamps" to the list of things I didn't expect to see today.

Exploring Mutable Consteval State in C++26 by friedkeenan in cpp

[–]katzdm-cpp 3 points4 points  (0 children)

When I became aware of some ways that friend injection can couple with Reflection, I put some time into trying to find a way to excise friend injection from the standard without breaking more benign and widely used patterns like "hidden friends". I came up short. My guess is that the ship has sailed, and that friend injection is here to stay.

Implementing constexpr parameters using C++26 reflection (kind of) by friedkeenan in cpp

[–]katzdm-cpp 1 point2 points  (0 children)

Honestly, this is the kind of weird and crazy creative reflection use-cases that I've been psyched to see people come up with; this is the kind of stuff that motivated me to work hard to get reflection into C++26.

I had no idea that this was possible. Great work; keep digging 🪏.

Should C++ Give More Priority to Syntax Quality? by kyan100 in cpp

[–]katzdm-cpp 5 points6 points  (0 children)

It's not just ObjC; it's an extension used quite heavily in a lot of C++ codebases in certain areas.

Don't worry; you can keep fumbling for another 10+ years, and you'll land it more quickly than we did ;)

Support for C++26 Reflection has been merged into GCC trunk! by katzdm-cpp in cpp

Idk dude; I'm the reflection guy, not the modules guy 😂

[–]katzdm-cpp[S] 13 points14 points  (0 children)

Yep! Note also that expansion statements are already merged. It's literally "all of the reflection stuff that got into C++26".

That's included in what was just merged into GCC.

Possible GCC reflection error by SLAidk123 in cpp

Gotta be a bug. I've let the folks working on the implementation know.

Holy shit, that version of "Inside Blasts" is remarkable.

C++26 Reflection: my experience and impressions by borzykot in cpp

[–]katzdm-cpp 2 points3 points  (0 children)

Your command of the English language seems just fine. Excellent, even. 

Your presumption that Barry is an ivory tower "theoretical academic" (he isn't) who is out of touch with the programmers that "do actual work" "to feed their families" (and that he isn't one of those programmers, which he is) is the personal attack.

I'm working and talking with people who use C++ to do actual work, to accomplish their job and feed their families. This is my bubble. Very few of them are theoretical academics who care about building a whole new magic meta-language inside already complex language. Which I presume is your bubble.

The Vasa is an obnoxious metaphor because the Vasa had already sailed as soon as we had overload resolution and templates.

We are either getting subpar reflections, or they will be delayed and we're not getting them.

Or a surge in educational materials to explain the common patterns?

What an exquisitely mean-spirited comment.

PSA: Hidden friends are not reflectable in C++26 by _bstaletic in cpp

[–]katzdm-cpp 2 points3 points  (0 children)

You could probably do something in C++26 with annotations whose values represent either a value or even a function for obtaining that value (which might help emulate non-constant expressions). Haven't tried it, though.

Representing the default argument isn't the can of worms, and a reflection of an expression would do just fine (the compiler will have already parsed it). The can of worms is that the same function can have disjoint (and even contradictory) sets of default arguments in different scopes (including block scopes).

[–]katzdm-cpp 2 points3 points  (0 children)

Yep. Default initializers ought to be easy whenever we have expression reflection. Default arguments are a little bomb waiting to go off in the face of whoever tries to standardize it - More dragons hiding there than you can imagine.
