Perhaps a small extension to (import ..) is warranted then, since the
underlying machinery seems to support aliases?
(import [the.java.package {Clazz1 Alias1 Clazz2 Alias2} Clazz3])
or, maybe more in keeping with require:
(import [the.java.package Clazz1 Clazz2 Clazz3 :rename {Clazz1
Alias1 Clazz2 Alias2}])
