specifically why it's harder to use than "new" and is not defined to
actually do anything.  I wasn't referring, in this paragraph, to
garbage collection.  Unfortunately, I put a side point about GC into
my post before continuing my main thrust, and this misled you.  Sorry.

Your discussions about the design reasons behind these points
(requiring a generic instantiation of U_D, not requiring U_D to
do anything) have been very helpful.  Thank you.
