I'd be surprised if a number is mandatory, but I'm not sure this should be part of some plugin (e.g. `LargeIntegers`).

Primitives 541-559 are used for SmallFloats and there's still some unused numbers after them (560 569). But I don't know how primitive numbers were reserved in the past. We might want to inform the Squeak/Pharo boards?
