I think the main point of interest is having a common Language Service Protocol.
Related question: is there a way to "Find All References" to a symbol or keyword that's smarter than just a text search? I actually haven't really missed this capability, but curious if there's a solution in proto-repl.
Yes, that does look like the interesting part. I was mostly just being facetious about expanding Atom to an "IDE" 🙂
That was actually my first thought when I read the headline. But found the LSP idea pretty interesting. There's a lot of implementations, I was surprised there was none for Clojure.
