@Andy Wingo
It's my mistake to call an incompatible constructor after I updated the interfaces. I think Guile-3 made more strict checking because this mistake wasn't caught before 2.9.

Now folks may use docker to try Artanis on Guile-3

docker pull

Best regards.

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.

Gosh we need to improve this info.  Anyway the procedure at
boot-9.scm:1153:19 is a record constructor, for a record with 6 fields.
Apparently somewhere in (artanis server server-context) is calling it
with the wrong number of arguments.  What do you use for records?  Do
you have your own abstraction or do you use R6RS records or something?
Perhaps something in artanis relied on the way that R6RS records used to
implement single inheritance, as a chain of objects instead of a flat
record.  Or perhaps the adaptations to R6RS records in Guile introduced
a bug.  I am interested to know the answer :)
