        Switch statements

        A switch statement is a way to change the flow of execution based on a variable value.

            A switch statement has the form switch on a followed by one or more
            when value statements where a is an expression,
            value is an expression compatible with a,
            and statements is a list of statements which will be executed whenever
            a matches value.

            Once the value is matched, and the corresponding statements are exectued, the flow of execution
            resumes at the end of the switch statement.
        
        
            
        
        

        Optionally, a switch statement can end with an otherwise clause and list of statements,
            which will be executed when no previous value matches. The otherwise clause
            must be after all the when clauses.
