(Formerly "Calico"). An object-oriented language from Bell Laboratories which uniformly represents all data as pointers to self-described objects. C+@ provides multiple inheritance with delegation and with control over which methods come from which delegated object; and default methodologies. It has a simple syntax with emphasis on graphics. It was originally used for prototyping of telecommunication services.
The language is patented by AT&T and Unir Tech has the exclusive license from Bell Labs to distribute C+@. Unfortunately Unir is owned and operated by well-known anti-IETF ranter, Jim Fleming, which may have had something to do with the language's rapid disappearence from the radar screen.
