Not Dune exactly, but having to run 'eval $(opam env)' in the terminal every time you open an OCaml project rather than the default being npm-like, where you can just open the directory and use the package manager command without having to think about it.
(writing all the below while being aware you likely know much more about OCaml than I do...!)
Possibly `eval $(opam env)` is something that should just go in your ~/.zshrc
The OCaml folks have done some work recently to improve the onboarding documentation, which I think is going in a positive direction
e.g. https://ocaml.org/docs/installing-ocaml (the eval as a one-off post install command)
And then guiding people to use 'switches' https://ocaml.org/docs/opam-switch-introduction, which I totally missed when I started with the language.
> Local switches are automatically selected based on the current working directory.
