Is this correct? You ask for 5.008, and that gets you 5.8?

    Yes. The other way to require 5.8 is to write:

    use 5.8.0;

    The problem with that is that v-strings (numbers with multiple dots) don't exist in Perl prior to 5.6.0. That means that instead of a nice message telling you to upgrade to 5.8 you get a syntax error. Check out what happens if you try to use just 5.8: 

    $ perl -e 'use 5.8'
Perl v5.800.0 required (did you mean v5.008?)--this is only v5.8.0, st
+opped at -e line 1.
BEGIN failed--compilation aborted at -e line 1.
