[PITCH] extractPayload for enum cases having associated value

This is a long requested feature that never saw the light. We have memories of other proposals pitched with Automatically derive properties for enum cases and before with Pitch: Even Smarter KeyPaths? from @stephencelis

[PITCH] @unrequired in function signature for optional closure parameters

From a perspective of a framework writer it is important to provide clear and understandable documentation for the correct usage of their APIs. Swift allows us to write functions that are at some extent self documenting, and clearly define what the function will actually do

[PITCH] Support for binary dependencies

This draft introduces support for binary dependencies in SwiftPM. It will allow vendors to upload artifacts for all supported platforms which will be resolved, downloaded and linked by SwiftPM. There are still some open things left, which can be found at the bottom, but we wanted to get community feedback before we continue with this.
