Woow, this is great news! I think it would be great towards importing it in Guile proper. To do that, I think we should first get Andy’s opinion on the approach. Then you could try to integrate the files into the Guile repo and adjust the makefile machinery so that it uses this code to generate the initial psyntax-pp.scm. There may be additional things to look at, such as performance when building from scratch. We could still include the generated psyntax-pp.scm in the tarball, like we do for some .go files, for those who want a faster Guile build and are willing to make this tradeoff. Thanks! Ludo’.
