Not sure if this is a bug or a limitation but this works:

While this produces a "No such device or address" error:

There's no guarantee that file descriptors opened with socket(2) show up in
/dev/fd. Bash doesn't emulate /dev/fd if the system provides it, so it's up
to the OS on those systems whether they do or not.
It doesn't generate that error on macOS, for instance, which has /dev/fd.
