From: Sarah Morgensen <iskarian@mgsn.dev> * guix/import/utils.scm (package-names->package-inputs)[make-input]: Return new-style package inputs. (maybe-list-field): Add procedure, which wraps BODY in 'list' instead of 'quasiquote'. (maybe-packages-field): Add procedure. (maybe-inputs): Use maybe-packages-field. (maybe-native-inputs): Use maybe-packages-field. (maybe-propagated-inputs): Use maybe-packages-field.
