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>?
