@benoit-pereira-da-silva Thank you! Could you please remove the extra commits? Codable support should go in a separate PR.

Sorry for hijacking this PR for asking this, but is the idea to keep compatibility with Linux or will that just be an after thought? Is there a CI that runs this in Linux as well to make sure it always works?

Hi @seivan; I sent an invite with commit access. Thank you for volunteering to do this!

@lorentey I Didn't, but I could look into it after seeing how Map performs compared to a Dictionary for my use-case on Linux.
