Well, in the case of classes, I don't think it would be very common.

For arrays it can be nice since you can assign back a slice of the array that you want to work with.

void main(string args) {
    args = args[1..$];
}

Otherwise I suggest you start labeling all parameters with in. Then you are prevented from modifying the reference, and can decide if it should be a ref parameter. Who knows, maybe you'll find a reason to leave it off.
