I would very much prefer to deal with it similar to how we deal with Guile-Newt or Guile-Charting: a soft dependency that’s entirely optional. But I guess that also depends on what Guile-Semver is used for. I just posted a question on this topic in that thread. :-) Thanks for reviving this patch series! Ludo’.
