  abstract=      "This article expands a concurrent language to support
     implementation inheritance by making block structures of the
     super process-class pluggable, and to interface inheritance
     by making the language's protocol inheritable. The parallel
     'object-based' concurrent language occam 2 has been used as
     a catalyst for the concept, causing the language in fact to
     become (almost?) 'object-oriented' (OO). The result is
     white-box reuse between a 'process-class' and its sub
     process-class, and black-box reuse seen from the client
     side. Since occam is aliasing free and considered a 'safe'
     concurrent language, the expansion we discuss here keeps
     those properties - somewhat unusual for an OO system. This
     new language should be well suited in safety critical
     systems, since it has inherited the static (compile-time)
     and analysable properties from occam proper. Basically, two
     new keywords are defined: PLUSSING and ROLLING. The language
     feature suggestion is on sketch level only and therefore not
     complete, no BNF description exists and no compiler has been
     written."
