Subject: bug#25154: 25.1; Bindings in cl-letf are in reverse order
Date: Fri, 09 Dec 2016 17:36:15 -0600 [thread overview]
Message-ID: <8737hwllow.fsf@gmail.com> (raw)
Compare the following:
(let ((x 5)
(x 6))
(+ x 10))
=> 16
(cl-letf ((x 5)
(x 6))
(+ x 10))
=> 15
This also occurs when using non-trivial places:
(setq v (vector 1 2 3 4 5))
(cl-letf (((aref v 1) 10)
((aref v 1) 20))
(aref v 1))
=> 10
I ran into this when using two different setters that sometimes
indirectly modify the same variable. The current behaviour makes the
result of that unexpected.
