If we’re lucky we might soon be able to assign to ‘self’ in class convenience initializers, addressing a long-standing language restriction: https://forums.swift.org/t/allow-self-x-in-class-convenience-initializers/15924

I think a wider audience than those who keep close tabs on the forums might find this useful, so I hope to put in a plug here:

A great number of questions are raised in these forums as to the functioning and design of numeric types and protocols in Swift. Sometimes, the answer can be found only by digging through the source code, and even then it's hard to place what you learn there within a larger context. Therefore, I've compiled a series of articles that delve into these topics in more detail.

[BasThomas]

Yes! Thanks, @xwu!

I think @BasThomas won't add it himself so I will do it. I think it's a great presentation about Swift language history.

[BasThomas]

Ha, thanks @fassko. Will add it! 😊

The constraint solver is now iterative rather than recursive — this should fix some stack overflow issues: https://github.com/apple/swift/pull/19203

SE-0227: Identity key path is accepted

In Swift, foo.self always evaluates to foo. So naturally, .self should be a valid keypath as well: https://github.com/apple/swift/pull/19382

Now we’re just waiting for tuple keypaths so we can have full parity between member access syntax and keypath syntax
