I'd really like to see a more extensible syntax for this. So:
use Dog 1.2.1; # ala Perl5
And then to extend:
use Dog { version => 1.2.1, cpanid => 'JRANDOM' };
This would allow arbitrary specifications, ie:
use Dog { interface => 0.2,
version => ['>=', 1.2.1],
company => 'Sun Microsystems'
};

Building off the above:
%{Dog}{1.2.1}{JRANDOM}
Or some such, with the longest-matching object winning.
