    A modest proposal: Allow “short” and “long” to be chained indefinitely, so “short short short short int” is a 2-bit integer and “short short long int” is 16-bit

        & unsigned should flip the bit, so unsigned unsigned is signed, etc

        Introducing the "short short short short short short int", which stores a single bit with 50% probability of correct retrieval.

        Of course, there's a 50% chance an incorrect retrieval still returns the correct value, so the read value matches the stored value 75% of the time. What a deal!

        Personaly, I'd prefer it if we could just chain the 'o's. So "long int" is 32-bit, "loooong int" is 256-bit, and so on.

        amendment: interpret mixed sequences of “short” and “long” as a binary search, rather than cancelling each other out short long int x; // 24 (or 48?) short short long long short int y; // 13

        Short long would be 48, and long short would be 24.

        More modest: You could just have one bit integers. Ordinary integers (and chars) can be provided by the standard library and a reasonably well optimizing compiler.
