I want to `close` an `HTTP` server after one connection. It seems to be impossible? The variable `server` is not defined at `close server`. ``` server <- createServer \request response -> do respond request response close server (pure unit) ``` It looks like this is impossible because the *Node.js* API is bad. `createServer` is just a wrapper for the *Node.js* `http.createServer` function. But still.
