Most of the statements I disagreed with were opinions.
"unsigned" means "I want to use modulo 2^^n arithmetic". It
does
not mean, "this is an integer which cannot be negative".
Opinion.
Using modulo 2^^n arithmetic is *weird*.
Opinion.
If you are using

Opinion.
I believe that
bugs caused by unsigned calculations are subtle and require
an
extraordinary level of diligence.
Opinion (correctly qualified as belief).
It's not only his "opinion", it's his *experience* and if we want
to play the "argument by authority" game: he most likely wrote
more production quality code in D than you did.
Here are some more "opinions":
