/// proceeds as follows:
/// The statement var id = e; is evaluated, where id is a variable whose name is
/// distinct from any other variable in the program. It is a compile time error
/// if the value of e is not an instance of the same type as the constants
/// e1 … en.
/// Next, the case clause case e1: s1 is executed if it exists. If case e1: s1
/// does not exist, then if there is a default clause it is executed by
/// executing sn+1.
