Are the things he illustrates already implemented in Clojure? I'm kinda new to Clojure and I see there is deps.edn and there is clojure.spec, but have they come together into the system he describes? Or is that still "in the works"?
I was left a little vague on how it'd work in the end. I guess your program would specify what spec/input-output it expects from a library's API and then the library git history is traversed till you hit the last "version"/hash that matches the spec you require. Then we can just get rid of version numbers entirely and I guess you would just get a warning when a library made a breaking change and your dependency is stuck on an old version/hash in the git tree
Am I understanding that right? I get that the new way of development he describes would prevent breaking changes entirely (though it honestly sounds messy with lots of legacy stuff floating around)
