There is a limit to the auto-generated constructors. This has been discussed
a few times before on the list -- try the gmane.org archive (which you can
use as an argument to site: to focus google queries).

stick 20 elements into list 1,
stick another 20 into list 2,
stick list 1, list 2, ... into bigList
