Consider this module:
--8<---------------cut here---------------start------------->8---
(define-module (t))
(define private #t)
--8<---------------cut here---------------end--------------->8---
And now:
--8<---------------cut here---------------start------------->8---

This is as expected.
But adding #:select (private) gives access to ‘private’:
--8<---------------cut here---------------end--------------->8---

$1 = #t
