You're correct -- this won't do what you probably intended. But the
great thing about private names is that this is a problem you can
*locally* fix. For example:
private myClone = installCloneLibrary();
var twin = [{a:0}, {b:1}].myClone();
var thing = MyObj.clone();
or
var cloneProp = installCloneLibrary();
var twin = [{a:0}, {b:1}][cloneProp]();
var thing = MyObj.clone();
will both do what you expect, without requiring changes to either
CloneLibrary or MyObj. --
