If it’s not actually intended to handle all JSON you should probably call it something else.

Hi Jon,

First of all, I'd like to point out that I've found your tone to be quite rude. Calling the design of Codable, that has gotten a lot of work from Apple and swift-evolution, as silly is insulting and can leave people hurt. If you have found it lacking, please say so: we're all here to discuss any feedback people have had with Swift. But please do so with respect for the people and the work behind it.

Now, concerning Codable, I find its name quite apt. It was never intended to be used a full JSON parser but as a strongly-typed Swift equivalent of Objective-C's NSCoding, which is nothing more than a framework for serializing and deserializing types into different file formats.

David.
