C++20 Feature Talk Heats Up At Latest C++ ISO Meeting

[plonoma]

I'm getting the impression the standards committee is trying to cram too much new specifications and material into an insufficiently large time-frame.
It would be better to put the new standard version in 2022-2023.
(A lot of the new stuff touches the standard libraries in huge, deep and drastic ways.)

Going through the following blog post:
What's in C++20 and the C++17 final score card: A report from Kona and look at the Toronto C++ meeting

Despite the lack of separate checking, I predict the current Concept will be incorporated into C++20 once all the defects are processed this year or next.

I wish they would have implemented separate checking.
Having a guarantee certain errors or kinds of errors being caught is a wonderful thing to have in a programming language.
A pity C++20 won't have this.

Maybe they can add that feature later?

there was no such plan. cairo was inspiration of api of 2d graphics ts, but now i heard they are switching to stateless api

There was, at least back in 2013-2014.

unsmart joke, of three major compilers only msvc doesn't ship full implementation of standard on same year these days and only of core language features, msvc library (and those are library features) is in good state thanks to stl

Not sure what you mean by "in good state thanks to stl". MSVC is always years behind competitors. Frankly, I'd imagine that's why they've started adopting clang into VC++ IDE.

Yes, finally! I wish the plan of merging cairo into stdlib was mentioned...

C++20: Unicode, Dates, Networking, Filesystem....

Implemented on every platform by 2023 ;-)

Syntax sweeteners are nice but those (very basic) standard libraries are two decades late!

Cool to finally have them, not too early.
