I know this is ancient, but since it's high on the Google hit list, I wanted to mention one thing...

This very cool trick does not work for @arrays. :-(

This:

    use Getopt::Long;
    GetOptions(
       'single=s' => \(my $single = ''),
        'multi=s' => \(my @multi  = ()),
    );

does *NOT* DWIM. According to "perlref":
As a special case, "\(@foo)" returns a list of references to the contents of @foo, not a reference to @foo itself.
I tried all kinds of permutations, and the best I could come up with was: 
    use Getopt::Long;
    GetOptions(
       'single=s' => \(my $single = ''),
        'multi=s' => do { use vars '@multi'; \@multi },
    );

which, isn't quite as clean, IMHO.

(It *DOES*, however, keep the variable declarations and command-line options on the same line, at least, so you don't have to make changes in multiple places when adding new options. *shrug*)
