I'm an idiot sorry about that. Okay, let's try again, suppose you wrote
SELECT * FROM t1 WHERE 2+2=4
Which is semantically identical to
SELECT * FROM t1
While the first is correct in that it has a semantic meaning and a valid output, wouldn't you rather have the system warn you that you've written something redundant? Because it's hardly likely a human would write the former if they meant the latter.
