    (server &opt host port env cleanup welcome-msg)

    Start a repl server. The default host is "127.0.0.1" and the 
    default port is "9365". Calling this will start a TCP server that 
    exposes a repl into the given env. If no env is provided, a new env 
    will be created per connection. If env is a function, that function 
    will be invoked with the name and stream on each connection to 
    generate an environment. `cleanup` is an optional function that 
    will be called for each stream after closing if provided. 
    `welcome-msg` is an optional string or function (welcome-msg 
    client-name) to generate a message to print for the client on 
    connection.
