    (net/read stream nbytes &opt buf timeout)

    Read up to n bytes from a stream, suspending the current fiber 
    until the bytes are available. `n` can also be the keyword `:all` 
    to read into the buffer until end of stream. If less than n bytes 
    are available (and more than 0), will push those bytes and return 
    early. Takes an optional timeout in seconds, after which will raise 
    an error. Returns a buffer with up to n more bytes in it, or raises 
    an error if the read failed.

    (net/close conn)))
# note: output doesn't actually start until you (quit) your repl's fiber:
(quit)
