Is (scm->employee) something (define-json-type) offers? Just having that would be great. I would be more tolerant to have guile-json as a dependency, since it's most likely lighter than Guix, probably already installed on the user system and it might me useful for users that are allergic to parentheses for configuration. > > (employee->json > (employee > (age 30) > (name "Foo") > (profession "Teacher"))) > > instead of: > > (employee->json > (scm->employee > '((age . 30) > (name .

If guile-json' license is compatible with Guix' license, I don't see any problem with taking the code from Guix and adapting it for guile-json. > > Sorry I couldn't provide any useful insight. > > Best, > > Aleix > > On Fri, Feb 5, 2021 at 9:24 AM Olivier Dion via General Guile related > discussions <guile-user@gnu.org> wrote: > >> Hello, >> >> In the module (guix records), there's some very nice syntax rule >> `define-record-type*` that allows very powerfull declarative style of >> records.
