// This tests excercises a number of switch things:
//
// Code to test for multiple-labels is different that
// code for a single label.
//
// Code for switching on strings is different from the integer
// code.
//
// nulls (for strings) need to be handled specially since ceq will
// throw an exception if there.
//
// null as a case statement needs to be caught specially
