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);
//flen_in and len_in will be the same
