> last time I actually tried to use C++20 none of the standard library implementations had std::format; has this changed now?

MSVC is the only major implementation that has std::format for now.

It's so funny to me that MSVC has become the cutting edge of C++ standards implementation. I remember starting out when it was a joke compared to Clang - although I was a novice, so who knows how complete my knowledge was at the time.

In any case, it's a really impressive effort from STL and the rest of their library team. STL has some incredible CPPCon talks, too.

One way you could interpret this (definitely not the only way) would be that Microsoft - or some group within Microsoft - sees C++ as a possible legacy system, with an opportunity to make a lot of money by judging correctly what customers want and how much income you need to justify that support as existing offerings rust out (so to speak).

Do you have any particular CPPCon talks to recommend ?

My favourite is "Abseil's Open Source Hashtables: 2 Years In" by Matt Kulukundis, Matt's a fine speaker but what makes it so fun is that Hyrum Wright is in the audience yelling interjections as a result of Hyrum's law (this is scripted). For example Matt explains a significant size optimisation for people who only have a few things in their map, it's just smaller with no other consequences - right? Hyrum points out that now rehash happens earlier, so if you depend on it not to invalidate references during the first 15 insertions you are screwed. Guess whether any real Google code did that...

I really love this talk in particular: https://www.youtube.com/watch?v=4P_kbF0EbZM (On charconv)

But any of the ones I've seen from Stephan have been fantastic, I think, although I'm not actually sure if I've seen more. He seems to have a lot of talks on very specific subjects, which can be really fun.

This sounds absolutely hilarious, I'll have to take a look.

I'm glad you liked my charconv talk! Here's a complete list of my recorded conference talks:

That's a way better list than what I had! Thanks! Think I'll watch the rand() talk tomorrow, I love (to hate on) rand.

I love the idea of placing a gadfly in the crowd to provide a dialogue.
