for a text input the relation between the two is trivial (they're both
strings). for a number input the relation is a bit more interesting so
i'll use that.

the first thing to realize is that the client-value will _always_ be a
string, while the lisp-value may be a string or any lisp object (like
a number). when we call the submit action on a form element it calls
the read-client-value method which converts (and validates) the string
the client sent into a lisp object and fills the lisp-value slot
appropiatly.

in code terms:

(when (validate-client-value form-element)
  (setf (lisp-value form-element) 
        (read-client-value form-element)))
