If you know how many arguments you can use, that
is perfect. Luiz's point is that if you don't, your easiest
recourse is a table constructor.

And, because it wasn't mentioned, there is always `select`. For example...

print("I received ", select('#', ...), "arguments")

for i = 1, select('#', ...) do

   print(

      ("The %d argument is:\t '%s' (%s)"):format(

         i,

         tostring(select(i, ...)), 

         type(select(i,...))

      )

   )
