It's obvious with Color, but when you deal with more complex stuff, code like

    computation_service.set_status(ComputeStatus::NotEnoughMemory);
    system.set_state(SystemState::Failure);

is a lot clearer than

    computation_service.set_state(.NotEnoughMemory);
    system.set_state(.Failure); 

in my opinion. Both objects/structs/whatevers can have a state type of their own but the shorthand form does not indicate whether or not the two can be used interchangeably. As a workaround, you could rename the setter to set_computation_state and set_system_state but then you're just repeating yourself in a different manner that's not as precise.
