[CM] pre-parsing scheme code

Nice code. But isn't the result of doing:

  s7_eval_c_string("(list 1 2 3)");

the same as the result of doing:

  s7_list_nl(s, 3, s7_make_integer(s, 1),\
    s7_make_integer(s, 2),\
    s7_make_integer(s, 3),\


Except that the second version probably runs much faster...
