The Standard C++ Foundation's annual global C++ developer survey is now open. As the name suggests, it's a one-pager:
2021 Annual C++ Developer Survey "Lite"
Please take 10 minutes or so to participate! A summary of the results, including aggregated highlights of common answers in the write-in responses, will be posted publicly here on isocpp.org and shared with the C++ standardization committee to help inform C++ evolution.
The survey closes in one week.
Thank you for participating and helping to inform our committee and community.

C++ coroutines: Basic implementation of a promise type
by Raymond Chen
From the article:
Last time, we diagrammed out how the pieces of a coroutine fit together. Today we’ll fill in the diagram with code.
Fortunately, most of the hard work has already been done for us by the result_holder class we already wrote. We just need to adapt it to the format required by the coroutine specification...

Just posted between the mid-month standards mailings:
d2349r0:
std::ponyby Ville Voutilainen
From the paper:
This is a proposal to lay to rest the long-standing question of whether C++ should optimize velocity or stability... This proposal has three things it proposes:
- two new decl-specifiers,
myandlittle, for the core language, and an accompanying name lookup change- the main library facility itself
- allocator support for the main library facility

A new blog article on an exciting idea for C++
Taming the power of C++ with AI
by Jens Weller
From the article:
In January Bryce Adelstein Lelbach gave a talk about NDVIDIAS CUDASTL fork at my online C++ User Group. Shortly after this talk was published on YouTube I got contacted by a start up, seeking feedback on their ideas of accelerating C++ with help of GPUs and AI...
