#ifdef HUMBLE_OPINION
Maybe you don't want to hear this, but how are you building the list?
If you must have access to the list in the order in which you seem to
be working on it above *before* you add elements to the list, then you
ought to keep track of the last cell, as well as scm_game_list.

If you are building the list first, then using it, but still need the
order, then it would be best to cons new elements onto the front, then
use scm_reverse_x (saving the return value).

If you don't care about the order at all, just cons new items onto the
beginning.
