Thanks, and thanks for the effort on jank !

Since you're here ;) : I read on the alpha doc that protocols and other part of the clojure object model are not done yet - is your goal to include them eventually, or is there a part of the lore of clojure that makes them not indispensable ?

Protocols, records, and the like will be implemented in jank. They haven't been prioritized for two reasons.

Firstly, historically, jank had a closed object model for performance, which I have blogged about here: https://jank-lang.org/blog/2023-07-08-object-model/

Over the past few years, I've been spending hammock time to find a solution to this to re-open the object model efficiently. I came up with a design this year which addresses the concerns raised in that blog post and opens up the object model, but jank today is still in a half-way state between the two systems.

Secondly, in the several years I've written Clojure professionally, I don't recall ever writing my own protocol, record, or struct. When I was first learning Clojure, I leaned on them more heavily, since I was coming from OOP land. But once I leaned into the pure Clojure data designs, the OOP side of things just stopped mattering. So, if I were to write just about anything in jank, I wouldn't intend on using these features. That alone has made them low priority for me.

But they'll be implemented. :) I'd estimate Q1 next year for me to tackle those.
