That's exactly what Adriaan is saying. With const the compiler can

With constref, you force it not to copy. But this is not so efficient

small parameter sizes.
So const will always pass records that are over a certain size by
references? That’s good to know since “const” is more pleasant to look
at it than constref. :)
As written above, the compiler can choose with const (and the choice may
differ for different CPUs and other factors), i.e. you shouldn't make
assumptions / rely on const of particular size to be passed by
reference.
