So you have never looked at Java, and seen its compiled class format, where unused slots are explicitly encoded in the format, these slots are reused, just like C/C++ reuses the storage slots of registers.
This is absolutely not fiction, it is real, and in fact essential for performance. Otherwise out machines would never have enough hardware registers. Performance would be also very slow.
