This paper describes the integration of concurrency control in
Balloon, an object-oriented language that separates the concepts of
type and class as well of subtyping and subclassing. Types are
interface specifications enriched with concurrency control
annotations. Classes are used to implement the operational
functionality of types as well as concurrency control mechanisms.
Types, classes and concurrency control annotations are independently
reusable and derivable. The language takes advantage of this
separation to solve the typical problems of the inheritance anomaly.
