I've been looking for the "correct" answer to these kinds of question
on comp.std.c++ too.  The questions being basically, what kinds of 
copies are allowed and/or not allowed, including in what situations
is a compiler allowed to make a copy at the same address as a previous
object, and do functions return by copy.

"Identity" seems to be a very poorly defined concept in C++ [ARM] today.
