Does the following sentence A Scheme implementation ("the system") raises an exception whenever an error is to be signaled or whenever the system determines that evaluation cannot proceed in a manner consistent with the semantics of Scheme. mean that a Scheme system must raise an exception whenever the R5RS says "unspecified" or is it merely allowed to raise an exception in such cases? -- Matthias
