The OP said Hoare had invented null (which is true), not that it was one of his achievement.

So? I said Tony would not like it listed as an achievement. I never said the OP listed null as an achievement (Which is True).

Let's not get too pedantic. The way I said it obviously implies that the OP listed null as an achievement. Similar to how the OP listing null alongside an achievement can imply it's an achievement.
