As an admirer of minimalism, who has given talks that extol Norman Wilson's streamlining of research Unix, I naturally like Forsythe's thesis. I noticed unintended irony in one more or less throw-away remark: "It is dangerous to place too much hope in any improvement coming from just following new fashions, if we lack insight into what really went wrong before. Without that insight, I suspect that rewriting UNIX in C++, for example, could easily become an excuse for increasing complexity (because by using C++ `we can handle more complexity')." Bjarne Stroustrup's avowed reason for building cfront, which evolved into C++, was to have a tool for building an operating system in object-oriented style. The tool took on a life of its own, and arguably became more complex than the old-fashioned Unix he aspired to improve on. Doug
