In Lua, nil isn't truly a first-class object, because it can't be stored in tables at all, either as a key or a value. The real problem, as I see it, is the widespread refusal to accept this fact. Well, no, I think we were talking about what # does. That # can be made better is probably mostly discussed in the hope to change its current behavior to something more satisfactorily or intuitive, if it should be changed at all. Which can't work, as has been shown, because the price would be to high. So it should probably simply throw an error. I'd perfectly seriously second eliminating it from the language or at least from the text books as second best option ... It really boils down to what audience Lua is for. A language that starts arrays with 1, mind you. |
