Ruby has two things over Perl: a reusable library built in the same object system you want to use (most of CPAN predates Moose and uses the brain-damaged vintage 1990 dispatch setup directly) and a culture of raising exceptions (rather than returning arbitrary bad values nobody remembers to check for). Sometimes I wish Ruby and Python could have merged, but it'd never work so long as Guido prefers expressing everything procedurally rather than in reusable block objects.
