I use this construct extremely often, as I think that allowing code lines to
wrap ruins the readability of indentation, but I'm quite disappointed that
the constant expression isn't compile-time evaluated:

luac -l -p -
x = "fff" .. "ggg"

main <stdin:0,0> (5 instructions, 20 bytes at 0x84f230)
0+ params, 2 slots, 0 upvalues, 0 locals, 3 constants, 0 functions
	1	[1]	LOADK    	0 -2	; "fff"
	2	[1]	LOADK    	1 -3	; "ggg"
	3	[1]	CONCAT   	0 0 1
	4	[1]	SETGLOBAL	0 -1	; x
	5	[1]	RETURN   	0 1
