Indeed. This works because of a bug in flet. Since it's
inspiration is Common Lisp FLET, it should make only a lexical
binding. The version I have has corrected this bug:
(macroexpand '(flet ((message (&rest args))) (f) (message "done")))
-->
(let* ((--cl-letf-bound-- (fboundp #1=(quote message)))
(--cl-letf-save-- (and --cl-letf-bound-- (symbol-function #1#))))
(unwind-protect
(progn
(fset #1# (function* (lambda (&rest args) (block message))))
(f)
(message "done"))
(if --cl-letf-bound--
(fset #1# --cl-letf-save--)
(fmakunbound #1#))))
