The default evaluator for `interaction' is analogous to
racket -l racket/base -i
where `pretty-print' isn't installed as the printer.
The example below illustrates how to install pretty printing into an
`interaction' sandbox.
----------------------------------------
#lang scribble/manual
@(require scribble/eval)
@(define ex-eval (make-base-eval))
@(interaction-eval
#:eval ex-eval
(begin
(require racket/pretty)
(current-print pretty-print-handler)))
@interaction[
#:eval ex-eval
(define (f x)
`(,(build-list x add1)
,(build-list x add1)))
(f 20)
]
@(close-eval ex-eval)
