That's better than vector-ref:
,@(for/list (((some-string some-list-of-vectors) (in-query ... #:group ...)
`(h1 ,(~a some-string))
,@(for/list (((some-vector) some-list-of-vectors))
(match-define (vector some-string2 some-string3) some-vector)
`(p ,(~a some-string2)
I would obviously preferred something like:
,@(for/list (((some-string some-list-of-vectors) (in-query ... #:group ...)
`(h1 ,(~a some-string))
,@(for/list (((some-string2 some-string3) (MAGIC!
some-list-of-vectors)))
`(p ,(~a some-string2)
