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

[pukkamustard]

Hi Erik,

There has been some work towards updating the OCaml packages in 
Guix (see https://issues.guix.gnu.org/47768).

A lot of packages have been updated so that there is a now an 
updated ocaml-X package for a previously existing ocaml4.07-X 
package. This includes a lot of ppx'es. 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?

Help is also required in reviewing the patches. The series has 
become quite large and hard to review (42 patches). If you could 
try them out that would be great.

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 :)

I have now applied the patches locally and tested a handful of the 
updated packages, and things appear to be working fine for me. Thanks a 
lot for doing this!

What is the process for getting these patches commited to master? Do we 
need someone to test that the patches didn't break any existing package?
