In the `scribble/text' language (which I think is what Butterick
uses), the right thing to use is `begin/text', which is kind of like
`list' but it allows definitions:
#lang at-exp racket
(require scribble/text)
(output @begin/text{foo
@(define bar "blah")
@bar})
Alternatively, when `scribble/text' is used as a language, the binding
is `text':
#lang scribble/text
@(define x @text{foo
@(define bar "blah")
@bar})
@x
