So is a multi-alternative case, as provided by Ada:
case Foo is
when 1 | 3 | 5 =>
statement1;
when 2 | 4 | 6 =>
statement2;
when others =>
statement3;
end case;
The difference is that Ada takes care of exiting the case statement
for you, whereas C requires (unsafely) that you use a break to avoid
being sucked into the code associated with subsequent cases.
