Not working under OCaml 5 - but I have working code.

Hi.

I wanted to use your library for a more lightweight syntax for a unit test framework I'm working on.

But installing it using opam failed miserably, I think due ppx_code is deprecated and incompatible with ocaml 5 (or at least other stuff I have installed)

I managed to replace the ppx_core with ppxlib, fix that part of the code, and also simplify some of the code depending on classes. I haven't used it extensively, but it appears to be working.

I'd not make a PR as such, as I don't know anything about opam packaging, and maybe it should also be dune-ified? I really don't want to spend time researching how to do that just yet (though I'd have to later if I was to publish my own code)

It's currently just in a branch, if you wish to update this.

Dunified and update code using your fork, thank you! Also tried dune-release to automate publishing to opam-repo, created a bit of mess in the process %) 0.0.9 version should be published to opam soon ocaml/opam-repository#25780.
