;; array parameter-type needs fields names to be something like
task[36], task[38] ... etc,
;; not with empty square brackets like task[], so the following wont work.
(define-easy-handler (process-page :uri "/process")
    ((tasks :real-name "task" :parameter-type 'array))
  (with-html-output-to-string (out)
    (print tasks out)))

;; but using this will allow you to use array parameter type, and thus
the above easy-handler will work

(define-easy-handler (form-page :uri "/")
    ()
  (with-html-output-to-string (out)
    (:form :action "/process"
     (:input :type "text" :name "task[0]" :value "37")

     (:input :type "text" :name "task[2]" :value "36")
     (:input :type "submit" :value "Process"))))
