I encounter similar behavior, but for dynamic padding, but it one case
it doesn't even work. I am using guile 2.2.6 from guix distro
scheme@(guile-user)> (format #f "~:{~v_ ~a ~}" '((5 "hello")))
FORMAT: error with call: (format #f "~:{~v_ ~a ~}<===" ((5 hello)) ===>)
missing argument(s)
In ice-9/format.scm:
1590:19 2 (format #f "~:{~v_ ~a ~}" ((5 "hello")))
197:20 1 (format:format-work "~:{~v_ ~a ~}" (((5 "hello"))))
In unknown file:
0 (scm-error misc-error #f "~A" ("error in format") #f)
error in format
Added the bogus 0 which doesn't do anything
scheme@(guile-user)> (format #f "~:{~v_ ~a ~}" 0 '((5 "hello")))
;;; <stdin>:3:0: warning: "~:{~v_ ~a ~}": wrong number of `format' arguments: expected 1, got 2
$1 = " hello "

Hello,
this is with current master, I don't know what stable 2.0 does, although =
I don't think it's changed there.
scheme@(guile-user)> (format #t "~{~{~a~^ ~}\n~}" '((1 2) (3 4)))
;;; <stdin>:1:0: warning: "~{~{~a~^ ~}\\n~}": wrong number of `format' =
arguments: expected 2, got 1
1 2
3 4
$1 =3D #t
apparently it only happens with double nesting, e.g. triple nesting is =
fine:
scheme@(guile-user)> (format #t "~{~{~{~a~^:~}~^ ~}\n~}" '(((1 2) (3 4)) =
((5 6) (7 8))))
1:2 3:4
5:6 7:8
$2 =3D #t
Regards,
Daniel
