The design of the unmodifiable collections would have been greatly enhanced if the wrappers included an indication of whether the thing being wrapped was already immutable, and there were immutableList etc. factory methods which would return a read-only wrapper around a copy of a passed-in list unless the passed-in list was already immutable. It would be easy to create user-defined types like that but for one problem: there would be no way for joesCollections.immutableList method to recognize that it shouldn't need to copy the object returned by fredsCollections.immutableList.
