Here's an example of how to escape interpretation, as well as the
implicit decoding that happens on strings:

---
#lang scribble/base

@(require scribble/core)
@(define (verb . elts)
   (element 'tt elts))

You can look at this: @verb|{hello world--- at verb[]}|.

In contrast, @tt{hello---again I am in a @verb[]}.

The idea is that Scribble provides a high-level and low-level
interface.  In the low-level interface, we're responsible for calling
decode-content, the function that (among other things) interpolates
"---" with em-dashes.  Also, note the use of the "|{" "|}", which is a
way to keep the inner "@" from triggering Racket evaluation.  See:

for more details.
