…utable Theoretically, loadimmutable inserts a placeholder into the contract to be deployed which is then replaced by setimmutable once the runtime code is loaded into memory. The interpreter is mainly used for differential fuzzing so we should satisfy that correct code never fails and we can still detect bugs otherwise, most of the time. Therefore loadimmutable is decoupled from setimmutable and just returns a random value (hash of the identifier), setimmutable is treated as a no-op.
