The Lua parser already handles consecutive concat's:

 $ cat i
 return a..b..c..d
 $ luac -p -l i
  
 main <i:0> (7 instructions, 28 bytes at 0x805af90)
 0 params, 4 stacks, 0 upvalues, 0 locals, 4 constants, 0 functions
	 1       [1]     GETGLOBAL       0 0     ; a
	 2       [1]     GETGLOBAL       1 1     ; b
	 3       [1]     GETGLOBAL       2 2     ; c
	 4       [1]     GETGLOBAL       3 3     ; d
	 5       [1]     CONCAT          0 0 3
	 6       [1]     RETURN          0 2 0
	 7       [1]     RETURN          0 1 0
