Scoped case statement in C++: purpose of cross-scope case labels? The case labels are just labels, destinations for (compiler-generated) gotos. In the same way as ordinary labels have function scope, case labels have switch scope. The only reasonable advantage is Duff's Device, which however is not very relevant on modern computers.
