Sorry to step in here. But there is no difference (as I see it) between
having a system library function that runs the motors and having a byte
code that runs the motors. It's all a matter of encoding. If I say:
set_motor_speed(MOTOR1, 20);
And that compiles to:
push 20
push MOTOR1
syscall set_motor_speed
... or whatever your coding scheme requires for a system library function
call, there is no difference between that and:
set_motor_speed MOTOR1, 20 // set_motor_speed is an opcode in the byte code
... except the encoding.
Encoding is an implementation detail. Can we talk about features?
