const_cast = code smell mutable = code smell Pretty much anything that breaks the contract is readily apparent when reading/searching the code, and indicates that something needs to be rewritten. Just because you can break the contract doesn't mean you should break the contract. Const correctness produces more readable/easily understood code. Don't be lazy, and make life better for anyone that has to maintain and use the code after you.
