Reduce code size
If the base register is zero, the data or constants can be in low memory, or high (negative offset) memory, such as ROM.
For the sake of brevity, lets suppose these changes will affect only the already declared classes: If the engine classes have constructors without parameters, we can use them and add constraint new to the EngineT parameter:.

It usually requires only one memory load, and minimizing slow memory operations is desirable.
