Hi, there’s a Guile 3.0.6 release planned that includes a rewrite of the reader in Scheme. It has speed in the same order of magnitude as the previous reader but might have different performance characteristics.
If I remember correctly, lilypond uses the reader a lot, so if you have a test-system with lilypond on Guile 3, could you test how running lilypond with the current Guile master from git affects lilypond? Best wishes, Arne -- Unpolitisch sein heißt politisch sein ohne es zu merken
