fnmap

Usage: (fnmap getter setter)
       (fnmap getter setter & keyvals)

Creates a fnmap, or functional map.  A fnmap behaves like an
ordinary Clojure map, except that calls to get and assoc are
filtered through user-defined getter and setter functions, which
operate on an internal map.

(getter m key) should return a value for key.

(setter m key value) should assoc key with value and return a new
map for m.

All other map operations are passed through to the internal map.
