Keynote: C++ Horizons - Bryce Adelstein Lelbach - ACCU 2023
Slides: accu.org/conf-previous/accu2023/
In the next decade, three major new C++ features will reshape how we write C++ code - reflection, pattern matching, and senders. Come join Bryce Adelstein Lelbach, one of the leaders of the C++ committee, to find out what's next for C++, and why you should be excited about it.

You're blowing my mind

When reflection came up, the first thing that came into my mind was ENUMS! I am totally sick of writing static string arrays that are basically only a copy of the enums along with a static to_string function. That would be totally usefull and is totally resolvale at compile-time!

@dangermouse1967 10 месяцев назад

I'm much less interested in the enum use-case. While I think it would be nice to have this for enums, it's pretty easy to do the enum thing now in generic fashion using the preprocessor and X-macros. It's not that ugly compared to what would be required to do something similar for class members. I think reflection is really powerful for the serialization use-case. I've wanted this for 20 years. You can't really do that with the preprocessor without writing every class in a dramatically different fashion, in a way that would make the code much more difficult to maintain. You could also do similar things by having every class use a tuple instead of regular data members, but it would be equally horrific and unmaintainable.

Senders unlock the power of the GPUs/CPUs with structured asynchronous contorl flow, reflection reduces boilerplate code and pattern matching replaces unreadable if else combinations. Give 'em to me , it want them NOW. Cannot wait to play with these features. C++ has a bright future ahead!

@mjKlaim 11 месяцев назад

Reflection does more than reducing boilerplates: it allows us to do serialization, data layout control and behavior conventions without any external tools T_T But yes.

@kuhluhOG 11 месяцев назад

@@mjKlaim sure, but quite frankly, most people will actively use it to reduce boilerplate library writers for serialization and the like will rejoice tho
