What is the sense of having the string only inside the scope? After the close brace, it can not longer be used.

I guess it's worth to add a hint that variables should be declared in its most inner scope which just spans the intended life-time at best. In certain cases, it's even useful to add an extra scope for a well-defined life-time of a variable. (E.g. it's recommendable for lock guardians or other occurrences of RAII.)
