Abstract

Subtyping is undoubtedly useful for the support of incremental refinement and reuse of software components, a crucial feature of object-oriented languages. Types and subtyping for concurrent languages are not yet explored sufficiently and tend to be less flexible than desired. We propose a flexible type model for concurrent languages. This model ensures statically that "message-not-understood-errors" do not occur at run-time even if object behavior is changed dynamically.
