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’.
