Would any of the people still on X3J11 like to comment? No, the block is the controlled part of the switch and it is entered via a case or default label, not sequentially starting at the block beginning. Declarations before the first label are valid, but no auto initialization is performed since execution does not "plow through" the declarations but instead bypasses them. The above is my understanding of what is supposed to be going on in a switch statement; my X3J11 notes are elsewhere at the moment.
