What's not native about Perl's OO?
It supports object creation natively:
bless({}, $class);
It supports inheritance natively:
$child->parent_method()
It supports method calling natively:
class->method(); # Static
$obj->method(); # Virtual
$obj->class::method(); # Non-virtual, Inherits
class::method($obj); # Non-virtual, Doesn't inherit
As a derict result of the above, encapsulation and polymorphism is natively supported. Perl doesn't support security divisions, but that's just a luxury (or a curse).
