Hi Vivien, Vivien Kraus via General Guile related discussions <guile-user@gnu.org> skribis:

As you know, ‘read-syntax’ appeared in 3.0.7, so it’s brand new and we could certainly extend (ice-9 read) with more features, including reading comments. In the meantime, I needed the ability to read comments in Guix, including with Guile < 3.0.7, so I hacked up this thing: https://git.savannah.gnu.org/cgit/guix.git/tree/guix/scripts/style.scm?h=core-updates&id=8419221620191d2988c22f6e7811d9ce1e0837bf#n50 It can read and write while preserving comments. Again, we could/should probably integrate that functionality in (ice-9 read) eventually, it shouldn’t be too hard. Thanks, Ludo’.
