I think a natural way of representing the request if this was to be
designed today would be to use alists all the way, perhaps with
optional arguments for adjusting how precisely the request itself
should be sent and handled:

(http "http://www.fsf.org/xyz/zyx"
        '((method . "GET")
          (path . "/")
          (headers . (("Accept-Encoding" . "UTF-8")))
          (form . (("param1" . "value1"))))
         :timeout 10)

This breaks compatibility of course though, as do any sensible changes
I can think of. So meanwhile I would be happy if the patch got
accepted, it would at least make the library at all usable to me, even
if not the easiest to use.

Cheers,
Jarosław Rzeszótko
