I just tried a guix build lua --with-latest=lua and it built version 5.4.3 without any issue (even with the patches it has). I don't know anything to test with Lua, but in a guix shell it reported the correct version and the interpreter ran (I looked up a simple print statement which did work).

If there's nothing in particular I should look for, I can submit a quick patch for this. Should the package be lua-5.4 or maybe lua-next? And should the current lua now inherit from this latest version?

I'm assuming for the lua system to be updated would need a staging or core-updates cycle, with guix refresh lua -l reporting "408 packages would ensure 782 dependent packages are rebuilt". So we wouldn't want to replace "lua" with 5.4.3 yet.
