In edition 1, he mentions it is possible to returns a const object
but none of the example are related to that and his examples
does not have top-level const qualifier. That is, he uses

    const char *

and not

    const char * const

for the return value.

I don't knows about edition 2...

In pratice, const is seldom used for return value and for arguments
as it provide not as much benefice in those cases as the effect is
