Crosses initialization of string and jump to label case case labels are really a lot like dreaded goto labels; they do not constitute a new scope.

Why I can't declare a std::string type in a switch/case box? A switch case is the same as a labeled "goto" statement. You are not allowed to "goto" a location in a block following the construction point of a local variable, and you can't do it with a switch either. The problem is, the string is still in scope at case 2. Each labeled section of a switch statement is NOT its own scope.
