You cannot get a lists proper length if there are lists inside that list, see:
world << length( list() + list() )
returns 0, while
world << length( list() + 1 )
returns 1.</<></<>

"list() + list()" combines two empty lists to get one empty list. You end up with list(), not list(list()).

"list() + 1" adds the element "1" to a list. You end up with list(1).

If that is truly the case, then .Add does the same thing and there is no way to properly append a list to another list without manual math.

l1[++l1.len] = l2

Also, if you fancy yourself a meatball:

l1 += (istype(l2, /list) ? list(l2) : l2)
