The switch statement as we see it in C and Java is due to the classic "multiway branch" based on a (single) discrete value. As K&R note (in their book), "falling through" has an advantage: it permits more than one case label in front of code to be executed alike for all values. The disadvantage is the necessity of using "break" at the end of such a statement sequence.
Other languages (Pascal, Modula, Ada,...) permit lists and ranges in case labels: hence there is no necessity for "break", and case branches are distinct alternatives. If the "switch" in the current proposal for Drools 6.0 has no (or no useful) interpretation of "falling through", then "break" should not be necessary. -W _______________________________________________ rules-dev mailing list rules-dev@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-dev
