If we write this code:
forum: copy [ ["Elément 1" "Colonne 1"] ... ]
this is what happens:
'forum -> [ ["Elément 1" "Colonne 1"]
Now after we build the layout, and the list is built,
this is the situation:
'forum -> [ ["Elément 1" "Colonne 1"] ... ]

second second get in lstforum 'subfunc
If we reassign 'forum, this is the situation:
'forum -> [ ["Sujet 1" "Date 1"] ... ]
[ ["Elément 1" "Colonne 1"] ... ]
^

second second get in lstforum 'subfunc
The list knows nothing about the change !
The list keeps its own word 'stuff, which points
to the original block, but unfortunately that
word is kept deep inside the list.
