Yeah, in this example.  Another would be

using NetworkConnection:
    .address = "127.0.0.1"
    .port = "8080"
    .connect()
    using .connection
       while .read():
           do something
    .disconnect()

I doubt anything like this will take though, since you can write
similar code with 'with' and assigning a long name to a short one.
