- Pitch: Make CodingUserInfoKey.init(rawValue:) non-failable

[aggie33]

I don't see why CodingUserInfoKey.init(rawValue:) is failable; I checked the implementation and it never returns nil, and it's trivial. If you are putting some custom data in the user info, you need to force-unwrap even though it will never be nil. Shouldn't we fix this?

A non-failable initializer could be added:

Simplify internals of Codable-related APIs

This proposal aims to simplify the internals of some Codable-related APIs, by adding two primary associated types and a non-failable initializer to the standard library.
