my( $dev, $ino, $mode )= stat( _ );
I disagree with introducing the $dev
variables here, given that they are not being used. Many languages will throw a "variable is initialized but never used"
warning if you do that sort of thing. Apart from that, I feel it makes maintenance harder because the maintenance programmer has more variables to visually digest ... and then perhaps ponder why they are not being used. For similar reasons, I dislike capturing parens in regexes when the captured values are not being used; I find myself visually checking the code for $1
, ..., wondering if I've missed something.
