This is achieved by storing the resources we need to acquire for interacting with the flipdot (socket fd and addrinfo struct) in a `struct flipdot` that is dynamically allocated and treated as an opaque pointer object via the BQN FFI. To make sure these resources are released correctly, we only provide a lisp style WithFlipdot to the user which takes care of acquiring and releasing the `struct flipdot`. This works even if an error occurs in the function the user provides thanks to _defer_. I'm not sure if calling it _defer_ is right since Go's error handling works differently, so defer really is deferred execution in a sense which doesn't really fit what we're doing here. The closest is probably Haskell's bracket, but that name references it's triadic nature which doesn't fit our implementation.
