confused by cons

[DanielAjoy]

I'm confused by this behavior of cons. It seems new items are added to the original empty list.

(() cons cons) ^list

$ "a" "B" list
 (
   "a"
   "B"
 )

$ "a" "B" list
 (
   "a"
   "B"
   "a"
   "B"
 )

$ "a" "B" list
 (
   "a"
   "B"
   "a"
   "B"
   "a"
   "B"
 )

That is not what happens in Joy

DEFINE
lista == [] cons cons .

2 3 lista .
[2 3]

2 3 lista .
[2 3]

Ohhhh yes, this could actually be a rather nasty bug. For some reason the same list is re-used within the lambda. I will need to investigate this further when I have a chance. Of course a PR would be welcome if you/anyone figures out why this is happening.

Moving to fixed as this was addressed.
