Legal Ada 95 example:

case C_function (params) is

    when 0        => null; -- success
    when Bummer   => raise Its_a_Bummer;
    when Darn     => raise Darn_it;
    when Blast    => raise Blast_It;
    when Disaster => raise Program_Error;

.......

Ada 95 does have

    exit <loopname> when <condition>;

and some folks thought

    raise <exception> when <condition>;

should be there as well.  But it was rejected.
