Hm, that's definitely an interesting idea. It occurs to me that there are a few things to "being strict" beyond type equality. For instance === will also (I think) stop PHP juggling *both sides* of a comparison, e.g. two numeric strings will sometimes be compared numerically rather than bytewise. Using if statements with non-booleans also feels closely related - should the setting (or another new flag?) throw an error on if($foo) being implicitly processed as if(empty($foo))?
