;;;; A package that calls the builtin get, imported by a program that defines
;;;; a get of its own.
;;;;
;;;; The importer's defn takes the name over in the importer's own file and
;;;; nowhere else: this file's names were qualified at the import (this
;;;; function is shadowed/field to everything downstream), so the get written
;;;; here is the builtin's, was compiled as the builtin's, and answers what a
;;;; dyn map holds under a keyword.

(defn field [m] dyn (get m :b))
