Glad to hear darktable builds with the newer version of Lua.

However, I realized belatedly that the --with-latest transformation will not inherit the patches of the original package. And, as I would have expected, those patches don't apply cleanly to the new 5.4.3 source. I haven't had a chance to investigate, and likely won't be able to for a bit (still catching up on other patches I have).

As for how to introduce the new version, my guess (now that the patches needed to be updated) would be to have a lua-5.4 (or called lua-next) package. If it is just the patches that need to be updated, lua (the 5.3 version) could inherit from lua-5.4 adjusting the source field for that version and using the original patches. Assuming this doesn't cause rebuilds of the lua packages, that is. If more changes are needed, then lua-5.4 would just stand separate from the lua <= 5.3 version set.
