I disagree (though I'm not sure exactly what you mean by
GET-POST-PARAMETER, which isn't a part of Hunchentoot I've ever
seen). If you need multiple parameter values for a given name, you can
pick them out of the POST-PARAMETERS alist easily enough:

  (defun post-parameters (name)
    (let ((alist (tbnl:post-parameters)))
      (loop for ((key . value)) on alist
            when (string= key name) collect value)))
