-               implementing lazy items with normal (non-bound) functions.

-               If deepcopy() raises a TypeError for a lazy item that has been added
-               via a call to addLazySingleton(), the singleton will be automatically
-               evaluated and deepcopy() will instead be called on the result.
+               This forces evaluation of each contained lazy item, and deepcopy of
+               the result. A TypeError is raised if any contained lazy item is not
+               a singleton, since it is not necessarily possible for the behavior
+               of this type of item to be safely preserved.
