'''
Shorthand decorator for the common case of looking up ORM objects from
named URL parameters.

For each named URL parameter passed to the view of the form
``db_table_id``, look up the ORM object in the corresponding model with
the given primary key, returning a 404 in case it is not found.

For example:

trevorc

(defn evens
  ([] nil)
  ([x] nil)
  ([x y & xs]
    (lazy-seq (cons y (apply evens xs)))))

trevorc

(defn factorial [n]
  (reduce * (range 1 (inc n))))
