For me those SQL team have made a mistake to allow any names
SELECT 4 AS [BAD+NAME],2 AS BAD,3 AS NAME
INTO #TEST

DECLARE @VAR int
SET @VAR = 2
-- you don't see difference with or without brackets
SELECT	[BAD+NAME]*@VAR
-- if you forget brackets
,	BAD+NAME*@VAR
FROM #TEST

-- after some time you give a difference!
SET @VAR = 3
SELECT	[BAD+NAME]*@VAR
-- if you forget brackets	
,	BAD+NAME*@VAR
FROM #TEST

DROP TABLE #TEST
and this
SELECT 4 AS [4]
INTO #TEST

DECLARE @VAR int
SET @VAR = 2
-- now you don't see difference
SELECT	[4]*@VAR
-- if you forget brackets
,	4*@VAR
FROM #TEST

-- after some time you give a difference!
SET @VAR = 4
UPDATE #TEST SET [4]=2
SELECT	[4]*@VAR
-- if you forget brackets	
,	4*@VAR
FROM #TEST

DROP TABLE #TEST
