ABCL (An object-Based Concurrent Language) is a family of *(programming language)s developed by _(A. Yonezawa) and his lab for "object-oriented concurrent programming". These languages are based upon a Lisp or Scheme core with primitives for *(object-oriented) *(concurrent) semantics (in other words, *(Actor)s). The language was further extended to use computational reflection (see _(ABCL/R)) to manage distributed computing and other language extensions in a way that is as seamless as possible to the user.
