Nice work by @gottesmang -- stronger compile-time checking of SIL ownership invariants caught a memory leak that was introduced in 2015: https://github.com/apple/swift/pull/24314

@gottesmang In addition to shaking out bugs Ownership SIL will let us write a much better ARC optimizer

New offset indexing pitch is up!

Convenient syntax for applying an integer offset to an existing index (with implied start/end if omitted), as well as slicing collections using only offsets. This approach implies linearity in the magnitude of the offset.

Interesting take on pitching. Anti-Pitch Just say “no” to protocols on structural types?

Pitch Receiver Closures

Allow specifying the receiver of a closure. (what a closure is being called on)
This would modify how self behaves inside a closure body.
Similar like in Kotlin.
