Why so many different uses of const?
In a function prototype (where there is no function body), qualifying a
parameter as const is just noise. The caller knows the function can't
modify any object in the calling context using that parameter since
that's just how call by value works.
Qualifying a pointer /target/ is useful in all cases where it can be
done. It tells the reader something useful about the function, and it
allows the compiler to check it.
