Just to once again clarify. There are two cases here
1. The parameter is a by-copy type (or a type that can
optionally be passed by copy). In this case, the advice
above corresponds to advice to avoid definite (or potential)
bounded errors. Important indeed! Note that the implementation
which raised an error was not only correct, but friendly, since
it is friendly for implementations to detect bounded errors.
2. The parameter is a by-reference type, in this case the
above advice is just a matter of stylistic considerations.
