I think that’s pretty cool! In a way, it also looks like a special case of the import-on-the-fly use case we discussed. Namely, if you could write: guix build json:./foo.json guix install pypi:itsdangerous … and have the relevant importer automatically invoked, that’d be sweet. But… that’s somewhat ambitious and shouldn’t block this improvement! Ludo’.
