Great to hear IUOs losing ground :-) Might adding additional compiler warnings as described in SR-104 accompany the implementation of this proposal well? https://bugs.swift.org/browse/SR-104

The proposal has been *accepted, pending implementation experience*: There is generally positive feedback on the proposal, as it keeps the good behaviors of the existing T! type syntax (including support for importing un-nullability-audited APIs, support for 2-phase initialization patterns, etc) while dramatically reducing the confusion and surprise that they introduce as they trickle through type inference. The core team sees significant value in having a simple and predictable model that can be explained concisely. That said, this is the sort of proposal that can have a profound impact on the actual experience using unaudited APIs. The core team believes that the experience will be good, but we would like to get some experience moving a couple of existing projects (both low-level code that interacts with C, and an “App” project working with high level frameworks) to see what the impact is in practice. If something unexpected comes up, we will revisit this, and potentially reject it later. Chris Willmore is working on an implementation of this now, so we should know in the next week or two. Thank you to Chris Willmore for driving this forward! -Chris Lattner Review Manager _______________________________________________ swift-evolution mailing list [email protected]<mailto:[email protected]> https://lists.swift.org/mailman/listinfo/swift-evolution
