Can't have a module called "React" and run dune utop

[davesnx]

Expected Behavior

Load utop with a file called React

Actual Behavior

→ ~/C/g/m/server-reason-react on main ✓ dune utop
File "_none_", line 1:
Error: Files packages/react/src/react.cma(React)
       and foo/server-reason-react/_opam/lib/react/react.cma(React)
       both define a module named React

Reproduction

git clone https://github.com/ml-in-barcelona/server-reason-react
make init
dune utop

Forgot that there's a PR already open about this #8735

I don't think there is much Dune can do here; utop already links to React, so you cannot link it again to it...

What about vendor React and Lwt inside dune and prefix them?

This strikes me as something that should rather be suggested to the utop maintainers, do you agree?

[davesnx]

Yes, that falls into utop. I will reopen the issue there: ocaml-community/utop#463
