There's no switch statement, only a Switch module, and you don't really want to use that, as the author himself says in Categorized Damian Modules. C.	[reply]

Perl has no built-in `switch` statement. The Switch module should not be used. As you don't show any code and don't show what problem you are trying to solve, I can't help you further.

There are a couple of alternatives to the Switch module, which don't share its weakness of being source-filtered. See Switch::Perlish and (my own) Case. Caution: Contents may have been coded under pressure.	[reply]

Your best bet is to avoid using Switch at all, especially in production code. It is very easy to introduce very hard to trace bugs and is just too fragile. If you have a large number of possible branches use a dispatch table, otherwise, if-then-else (or ? : ).	[reply]

sicone, As has been pointed out, using Switch in production code is discouraged. This will be mostly remedied in Perl6. Dispatch Tables don't offer the same degree of flexibility, but for specific problems are a great solution. Cheers - L~R	[reply]
