@BasThomas If there is nothing incredibly important, I would like to suggest postponing this issue until next week, given the unrest across the US right now.

@BasThomas If there is nothing incredibly important, I would like to suggest postponing this issue until next week, given the unrest across the US right now.

Sure, I'm ok with that. While I also wouldn't mind to publish (it might be a welcome distraction to some) postponing a week works, too.

For your information, I then do plan to write and publish issue 162 on June 18, a week after this issue, as there's a sponsorship that I don't feel like moving around :)

[jessesquires]

Sure, I'm ok with that.

Thank you @BasThomas @fassko. I appreciate you ❤️

Yes, perhaps. However, I would argue that the luxury of distraction is mostly (or only) afforded to folks whose communities have the privilege of not being directly affected by police violence.

SE-0282 (Review #2): Interoperability with the C Atomic Operations Library

Draft PR: Multi-statement closure type inference.

Introduce support for type inference of closures with multiple statements. Type inference flows from the closure parameters through the body of the closure to determine the return type. This, for example, allows a "map" closure with multiple statements to infer the result type based on the "return" in the body:

let _ = ints.map { i in
 let value = i + 1
 return String(value)
}
