Hi Wingo! Here're update: 1. 2.9.9 didn't fix this issue 2. I imported r6rs record-type in (artanis utils), and this module was imported in almost every artanis modules. I do use r6rs specific record API to introspect the internal things for debugging in Artanis. And I imported r6rs define-record-type in server-context.scm I guess there're some name conflicting.
