// This test verifies that when a late variable is read prior to its first
// assignment, and the read occurs within the body of an unlabelled case block,
// and the assignment occurs elsewhere in the switch, that there is a
// compile-time error, because the variable is unassigned on all possible
// control flow paths to the read.
