Opens a non-blocking IPv4 socket like <a href="udp-open.html"><code>Udp.open</code></a>, but bound to <code>127.0.0.1</code> alone: programs on the same machine reach it, and nothing on the network can. Use it for a port only local tools should talk to, such as a development link. Returns the handle, or <code>0</code> when it could not.
```ludic
program Demo {
entry {
let s = Udp.open_local(port: 0)
print(s > 0)
}
}
```
