Import does not demand name mapping. You can import a full path without
aliasing. This will work fine:
(ns multi.core
(:require [multi.ns1]
[multi.ns2])
(:import [multi.ns1.Animal]
[multi.ns2.Animal]))
(multi.ns1.Animal. "hi")
(But remember to use the keyword :import, not the symbol. This will be
tightened up in the future.)
