comment Sets. Classes. …?
No, if you have Cantor-diagonal-style machinery available you are dealing with sets. Classes are really there as a catching net for the paradoxes of set theory (so Russell's Paradox escapes being a paradox because the class of all sets where $x \notin x$ is not itself a set).

comment Pick's Theorem on a triangular (or hex) grid
