I fully subscribe to that. Well said!

One more note I cannot resist here: reformatting/restyling sometimes "improves" readability for some where it "obfuscates" for others. When in a team get consensus.

Some changes might yield the same underlying code and thus seem to be just styling:

$ perl -MO=Deparse -e'$a = 1 unless $b;'
$a = 1 unless $b;
-e syntax OK
$ perl -MO=Deparse -e'$b or $a = 1;'
$a = 1 unless $b;
-e syntax OK

but where some see a change from first to second or vice versa as a readability improvement, others might percieve this as plain obfuscation. Not all minds work alike.
