Ah, I see. I guess I'm so used to writing cases with break's that I forgot
that C/C++ semantics allow cases to fall through to the next case. I had
intended the semantics to be:
switch (choice) {
case A: {
someobj x;
...
}
break;
case B: {
...
}
break;
...
}
Obviously, this isn't the case with what I actually wrote.
