Object oriented programming focuses on bundling together the data with the operations that can be applied to them. Access specifiers allow you to control the invariants of the type, and deterministic destruction of objects provides the glue that makes management of all types of resources.
But homogeneous does not mean trivial, and attention has to be paid. In a language with exceptions special care needs to be taken so that resources don't leak, but resources are not the only problem, when we model a domain, we need to maintain the invariants on top of which our algorithms are built.
