Hi, https://gitlab.com/lilypond/lilypond/-/merge_requests/1127 is about to be merged, so a heads-up for everyone using Guile 2 and byte-compilation: if you get weird errors about a "wrong number of arguments to markup-lambda", you need to clear Guile's byte-compilation cache in out/share/lilypond/current/guile/. As far as I understand, this is because it does not recompile files using a macro when the macro changes in spite of having relied on the macro definition for the compilation, so at execution everything goes wrong.
Regards, Jean
