Subject: bug#71120: 29.3; buglet in cl-loop
Date: Wed, 22 May 2024 10:43:36 +0200 [thread overview]
Message-ID: <23fd70f8-6e01-45d7-b9f9-d81d53c95ffd@lmf.cnrs.fr> (raw)
When I need a list of 100 random dice throws I write
(cl-loop for i from 1 to 100 collect (random 6))
It compiles just fine.
If instead I use
(cl-loop for _i from 1 to 100 collect (random 6))
then I get a compilation warning:
foo.el:1:18: Warning: variable ‘_i’ not left unused
It should be the other way around.
The variable 'i' is unused in the first form and that deserves a warning
at compile time. Otherwise the compiler will not help me catch the typo in
(cl-loop for i from 0 to 10 do
(cl-loop for j from 0 to 10 do
(foo j j))) ;; <<<=== typo, I meant (foo i j)

to all involved!!)
