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).

Recurse:  

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