The function would be given to the client so it can write the data to
the server. For example:

(... #:data #"Here's the post data")

would be the same as

(... #:data (\ (op) (display #"Here's the post data" op)))

It's the HTTP connection's OUTPUT (to the server) port, not its INPUT
(from the server) port.

The return happens internally to the http-client and it doesn't have
any reason to use any value produced.
