Is there a good reason why we cannot (as of 2.1.1) deepcopy complex objects?

I doubt it.  Works fine in 2.2:

Python 2.2 (#28, Dec 21 2001, 12:21:22) [MSC 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import copy
>>> z = 1-1j
>>> copy.copy(z)
(1-1j)
>>> copy.deepcopy(z)
(1-1j)
>>>

The copy module got quite an overhaul for 2.2, and that likely fixed many
odd old bugs.

The right place to look would have been the Python bug database on
SourceForge, but I didn't find a specific bug report there either.  That is
mildly strange.  It's not strange that the 2 people using complex numbers in
Python didn't add a FAQ entry, though <wink>.
