Im not sure how what the 'prefer' is about -- your specific num
wrapper or is it about the general question of choosing mutable or
immutable types?

If the latter I would suggest you read

[And remember that Stepanov is the author of C++ STL, he is arguably
as important in the C++ world as Stroustrup]
