[swift-evolution] [Proposal] Struct syntax for requesting a copy with an ivar set to an explicit value

[Nevin Brackett-Rozinsky]

As an additive proposal this is out of scope for Swift 3. Discussion of
additive proposals resumes August 1.

This functionality has been discussed on-list before, especially regarding
a global “with” function. I believe Erica Sadun has a particularly elegant
implementation.
