Notes
A faster and lighter (in bytecode) way to determine the length of a script is to do a not-equals compare with a null list. This works because the list not-equals compare returns the difference between the lengths.
list in; integer len_in = llGetListLength(in); integer flen_in = (in != []); //flen_in and len_in will be the same integer neg_len_in = -llGetListLength(in); integer fneg_len_in = ([] != in); //fneg_len_in and neg_len_in will be the same
