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.
