Feature request: Experimental effect syntax support?

[Zeta611]

I'm currently using 5.1.1+effect-syntax variant, and ocamlformat (obviously) fails to work.

Describe the solution you'd like
I have actually implemented a rudimentary support for the syntax here for personal use.

But I'm not sure whether or not or how I should contribute, as this is an experimental syntax support.

Additional context
It works:

This is awesome ! I think you can definitely open a PR as the effect syntax is to be released in OCaml 5.3 (I think?)

Great, I've opened it in #2562!
