|I'm fine with that too .. the real issue was "is there a need to agree on a way, and what, if so, is that way?"|
I agree that the elegance is not to be lightly discarded. In this discussion I am not understanding what is wrong with using nan as a place holder to make a table have array like properties. To my mind another advantage of nan is that string.format will not choke on it the way it does on nil.
