[bug#47768] ocaml - how can we get more recent version of core-kernel and common ppx'es

["erikl@posteo.net" <erikl@posteo.net>]

Great, this is exactly what I was hoping to find! I had of course forgotten to search the debbugs and in the devel mailing list there were only really old threads about the 4.07 stuff. 

Thanks for your work here, I will test your patches and let you know :)

However not everything has been updated yet and there are still a few packages missing to be able to update ocaml-core-kernel. But maybe you could use the #47768 as a basis and update some packages towards ocaml-core-kernel?
