Hi Maxime,

thank you for investigating!

Maxime Devos <maximedevos@HIDDEN> writes:
> scheme@(guile-user)> (null?)

This is a correct warning: null? requires an argument (the list to check
for emptyness). The path forward from here is to find out why null? does
not receive an argument.

Best wishes,
Arne

Hi Maxime,

thank you for investigating!

Maxime Devos <maximedevos@HIDDEN> writes:
> scheme@(guile-user)> (null?)

This is a correct warning: null? requires an argument (the list to check
for emptyness). The path forward from here is to find out why null? does
not receive an argument.

Best wishes,
Arne

Yes, the warning is correct. I wasn't referring to the warning, but to the =
compile
error.

scheme@(guile-user)> (null?)
;;; [the warning]
While compiling expression:
Wrong number of arguments to #<procedure 7fad2ea94660 at language/cps/types=
