That only works in Scheme/Racket code if no unbalanced "|#" appears in
the region that you want to comment out, of course.

Eli made Scribble's at-exp notation more general: It lets you pick the
brackets for a comment after `@;', so you can pick a closer that isn't
used in the region to comment out.

For example, to comment out a single "}",

 @;{
   }
 }

would not work, but

 @;|{
   }
 }|

works.
