Don't take my word for it, but I think that if your ordering function is wrong (as in, not consistent) then table.sort can end up passing nil as one of the arguments to the ordering function. If you

2009/7/21 Sam Roberts <vieuxtech@gmail.com>: To avoid that problem you can use the parameter passed to modules, which is the module name. So a better implementation of bye.lua would be: % cat hi/bye.

Maybe I misunderstand what you mean by "namespaces are automatically created for you", because it doesn't look like it to me. I would expect after require"hi.bye" to be able to access "hi.bye", if na

Thanks. This is for table.sort, right? Can this result in different answers for exactly the same code and data? If so, I'll go through the code and look for any occurrences of this. Steve

In any event, with exactly the same input data and exactly the same code, how can I get different results on successive runs? Could I have an uninitialized variable? I didn't think that was possible
