Add CodingKeyPath proposal

[calda]

Swift Evolution thread: CodingKeyPath: Add support for Encoding and Decoding nested objects with dot notation

• Previous revision: Add support for Encoding and Decoding nested JSON keys

Implementation: swiftlang/swift#30570

• Sandbox prototype: calda/CodingKeyPath

[calda]

@airspeedswift Are there any actionable next-steps that could move this proposal towards a formal review?

• Reception from the community was reasonably positive in the two pitch threads [1, 2]
• This proposal has an implementation ([Draft] Add CodingKeyPath swift#30570)

hi @calda, apologies for the slow response. do you mind launching a new pitch thread on the forums on this idea, as the team has some feedback best given in the context of a pitch.

Thanks for the response @tomerd -- would you mind sharing feedback on the existing thread (https://forums.swift.org/t/codingkeypath-add-support-for-encoding-and-decoding-nested-objects-with-dot-notation/34710/26)?

I don't have any new information to add (that isn't already present in that thread) so I would feel a bit silly creating a new thread from scratch. I can find time to start a new thread if that is your strong preference, though.

that can work too. I will point the folks that had feedback there.

@calda given our recent discussion on the pitch thread with @parkera, should we close this PR, or do you want to amend it?

[calda]

We can close this one. Thanks for your feedback and suggestions!
