Just a minor note on the difference in our solutions with respect to Exporter: Perl 5.6 and earlier require Exporter to be subclassed, not just imported. 

use Exporter qw(import); # Perl >= 5.8
use base 'Exporter';     # Perl <= 5.6

Even my solution isn't backwards-compatible prior to Perl 5.6 because I included our and warnings. For personal use, this may not matter, but module authors who plan to publish should keep it in mind.

Update: For Perl >=5.8 I changed the example to note that you need to specify import.
