I really like this goal but can't help feeling that we're stretching C beyond its limits here, so that the client code ends up boilerplate-heavy. Kind of like the issue with local_err elsewhere in this thread, where you juggle things instead of a "throw Exception(...)". What does the client code looks like for link<PCIDevice>? -- error compiling committee.c: too many arguments to function
