in reply to Perl 5.10: switch statement demo

Judging by how often people forget to place break;, it's much more natural for us to think of cases as exclusive. Or maybe it's because it's much more common to want exclusive cases, in which case it also saves us needless typing.

    I dunno -- remembering to add the break; is just one of the things that I know and will never forget when I write C. You can call it a feature or a bug, but it's part of the language that I know.

    I didn't write the node to complain, really, it's more of a warning for anyone else who grew up writing C. And it's spawned a couple of really good responses detailing alternative approaches that work, both before and after 5.10. And that discussion, by itself, is very useful.
