Expr\List will now contain ArrayItems instead of plain variables. I'm reusing ArrayItem, because code handling list() must also handle arrays, and this allows both to go through the same code path. This also renames Expr\List->vars to ->items. TODO: Should Expr\List be dropped in favor of Expr\Array with an extra flag?
