BTW, there is another approach:

Describe what your function does properly.

For instance, use terminology that a libc-level programmer will
recognize as implying use of particular libc interfaces, which they can
mentally maps back pledge concepts.

(This reminds me of the warts in libc we got rid of -- to allow the
creation of pledge.  syslog() doesn't use sockets.  DNS is a special
socket, and regular sockets can't do DNS.  isatty() is used extensively
in libc, so it abstracted out to ensure ioctl is taken away.  Various
things like this were taken away inside libc, so that programmers don't
need to be shocked "That operation seems so simple, why does it do
something so complicated which I never expected?"
