I am not sure about that. Unless there is an expensive copy
construction, most objects are simple data copies.
To use 'ref' or not should be guided through semant

You can live without 'const' until your code interacts with other
people's code. For example, the following program works just fine:
struct S {
int * p;
void foo() {}
}
void bar(S s) {}

Const is used for you not be able to change your values inside
