1. I agree. And this is being worked on, in the future dune will take on more package management tasks.
2. Agree, YAML has decisively won the config format wars. But dune it's extremely unlikely that dune will change this, and we can at least tell ourselves that s-exprs are pretty cool after all.
3. Yup, I hope Eio becomes the de facto standard in the future.
dune init …
opam install some tools like lsp
restart vscode
dune build --watch and I’m good to go.
