If I'd use 'BOOLEAN, how can I know when the value of a boolean is NIL
and when a boolean isn't supplied?

Consider (foo :parameter-type :boolean :request-type :get)
example. Both "foo.html" and "foo.html?foo=" returns NIL for FOO
variable. IMHO, for the formal case, there should be an exist-p
switch.
