Re: possible bug in varibale length arguments

[Dimitris Papavasiliou <dpapavas@...>]

Try ipairs({...}) instead of ipairs(arg).  You access the vararg list
as ... instead of arg since Lua 5.1 and it is a list, not a table so
you need to pack it inside one if you're going to feed it to ipairs.
If using Lua 5.2 you can also do table.pack(...) instead.
