I'm a huge fan of the ideas behind this library. Using the stable ABI of "magic numbers" is brilliant. Would love to see this solution gain more usage!
That's like saying the '9' in kill -9 might change someday. However it really does depend on which numbers. In the APE blog post I mention the importance on focusing on the subset of numbers that systems share in common. In other words, the really old ones. https://github.com/jart/cosmopolitan/blob/master/libc/sysv/c...
Not quite–kill is part of POSIX, and platforms that expose a libc interface must keep signal numbers consistent for applications. Syscall numbers need not be stable if they are not exposed, as is true on pretty much every platform but Linux.
