in reply to Switch Module on Perl 5.8.0

The Switch module mistakenly escaped into Perl 5.8. Do not use it. The Switch module was deprecated in Perl 5.10 and removed in Perl 5.14.

Notice that in Categorized Damian Modules, the Switch module is categorized by its author as "Damian modules you shouldn't use in production because their purpose is to explore and prototype future core language features".

You can switch to the built-in given/when if using Perl 5.10+. If stuck with Perl 5.8, I'd just use an if/elsif block instead.

    I'd agree with everything else everyone has said in this subthread, except this:

    The Switch module mistakenly escaped into Perl 5.8.

    Switch was deliberately put into Perl 5.8 for a very clear and specific purpose; a purpose that was eventually achieved in Perl 5.10.

    Think about it ;-)
