Subject: bug#27674: 26.0.50; cl-progv: strange scoping due to implementation
Date: Wed, 12 Jul 2017 23:53:01 +0200 [thread overview]
Message-ID: <87lgntfhky.fsf@drachen> (raw)
Hello,
The way `cl-progv' is implemented, we have some strange effects
happening to closures in the body. For example, with lexical-binding
on,
(let ((x 0))
(cl-progv (list 'x) (list 1)
(funcall (lambda () x))))
yields 0, and
(cl-progv (list 'x) (list 1)
(funcall (lambda () x)))
yields 1. That isn't consistent (FWIW I would expect `1' in both
cases).
TIA,
Michael.
