Apparently there is BlockContext>>newProcessWith: anArray "Answer a Process running the code in the receiver. The receiver's block arguments are bound to the contents of the argument, anArray. The process is not scheduled." <primitive: 19> "Simulation guard" ^Process forContext: [self valueWithArguments: anArray. Processor terminateActive] asContext priority: Processor activePriority but no equivalent for Closure. Is is normal? Stef
