I too am a big fan of consistency.  We would be more consistent (IMHO) if we
dropped the option of no parentheses from function calls.  I think we could then
remove commas from the language (or at least make them optional).

function test(a, b, c)
   print "note"
   for i,v in ipairs(a) do
       b = {1, 2, 3, "boom", {4,5,6}, }
   end
   return a, b, 15, "ok"
end

could become


function test(a b c)
   print("note")
   for i v in ipairs(a) do
       b = {1 2 3 "boom" {4 5 6} }
   end
   return a b 15 "ok"
end

This feels much cleaner and consistent to me.
